No helper points, but AF points can be grouped together. This could also be very helpful.

You're right- the ability to customize AF expansion is arguably just as important as the placement of the AF points and the accuracy in the 1-series bodies. I'd also like to have tracking sensitivity. The ability to customize the dynamic AF points and sensitivity would make it a hit with action shooters.

Although the smaller sensor will make it less popular for video compared to the 5D II, the ability to do 720/60p would be very nice, as would the ability to customize the frame rate between 24, 25, and 30.

3) AF with f/5.6 or faster lenses
If this is correct, then it means that it is a new AF system and not just the system from the 1D series cameras. It will be interesting to see exactly what the AF system is. Is it based on the diamond pattern from the XXD series or based on the 1D series? Are there helper points for tracking or not? These details will be important.
Well, it could be the 1D AF system without assist points AND AF limited to f5.6 by firmware.
That way they could save money by using the same AF.
Remember that the 40d already had the ability to film.
Canon just chose not to enable that feature in firmware. As in the 50d as well.

canon didn't design them to do film. how would they record the sound?

Because they didn't want to.
The camera has everything needed to film, as previously proven by a hacker.
It's all firmware, except fo the sound, as you mentioned.
But the inclusion of a small microphone should not have posed a significant chalenge to the design team.
It would have been something very easy to implement in the camera.
The 50d case is even more flagrant.
They just didn't want to, since, when the 50d was released, the 5DMII was already in the final stages of development.
They wanted the 5dMII to be the first canon to shoot video.
Perhaps to divert the attention from it's AF system...

bits that I found interesting
==========================
" The new use of the central 8 to double cross, all 19 points cross-type AF system, a rich selection of focus modes and a maximum of about 8 per second"
"By using two high-performance DIGIC 4 Digital Image Processor composed of pairs of DIGIC 4, to ensure that the camera as a whole has a good reaction speed,"
"Accompanied by quality improvement focus accuracy requirements become more stringent, EOS 7D uses a central 8 to the double cross, all 19 points cross-type AF system."
"8 frames / second continuous shooting speed of 126 consecutive shooting (JPEG Large / U ※ Based on Canon testing using a standard Ultra DMA (UDMA) memory card)."
"Equipped with a "double-63 zone metering sensor," able to detect color information, and can use 19 automatic focus-focus information, together with stable exposure. Integrated Metering Systems by iFCL (i = intelligent, F = focus of information, C = color information, L = luminance information) control, even in previously difficult to obtain an appropriate exposure scenarios can also be obtained by virtue of the new algorithm the correct exposure."
"EOS 7D also features the "auto-focus fine-tuning,"
"in addition to containing the "single-point auto-focus", but also has a focus range than single-point AF Focus range of smaller "fixed-point auto-focus," "
"single-point auto-focus" "fixed-point auto-focus," "automatic extension of the focus"
" "regional auto focus"19 pairs were divided into five focus areas"
" EOS 7D uses a newly developed non-contact electromagnetic rotary speed electronically controlled mechanical focal plane shutter, and its basic structure inherited the EOS 5D Mark II has been successfully applied on the shutter unit. And use with the EOS-1D series
of the same material, reaching about 15 million times a shutter life."
" EOS 7D inherits the EOS 5D Mark II's basic structure, using a durability test more than 150,000 times the shutter unit."
this is more realistic.
"three-dimensional electronic level " in the viewfinder
"to gain a more accurate exposure, the metering sensor also has the detection of RGB three primary colors R and B wavelength wavelength of color measurement features, and according to available information correctly to improve the red Pishe Ti prone to the phenomenon of lack of exposure. In addition, the 19 AF points correspond to a corresponding metering area, so you can refer to each of the focus in the distribution of brightness as well as other ways to get out of focus and then calculate the amount of exposure value."
" EOS 7D has a 160 ° wide viewing angle, and 92 million points of high-precision, "3.0" clear display LCD Monitor II-type. "LCD Monitor-II clearly show the use of optical elastic material for the replacement of the original LCD monitor and LCD panel protective layer The gap between the (air layer), which resolved by the protective layer and air layers of different refractive index caused by external light reflection problems."
"The adoption of sealing parts departments, as well as decorative skin tight structure so that the camera has a better performance of water droplets dust. "
"EOS 7D not only reached about 18 million effective pixel, but also achieved a low noise performance of the fine image. CMOS wafer process into a more sophisticated production process, not only solved the cause of the high pixel area of each pixel to narrow the problem, but also uses a higher photoelectric conversion efficiency of the new photodiode. In improving the pixel sensitivity at the same time, the transistors within a pixel was modified to achieve a higher S / N (signal to noise) ratio. In order to effectively improve the condensing rate, in addition to using non-gap micro-lens technology, also used to reduce the micro-lens to the photodiode from the new technologies"
"Image signal transmission is the sequence of the single-channel high-speed reading, while in 8-channel high-speed reading. Compared with the EOS 50D is about 1.3 times faster to achieve about 8 / s high-speed continuous shooting. Low-voltage power supply of high-speed amplifiers and a variety of energy-saving measures adopted to achieve the low power consumption."
" In addition, can be realized per second 30/25/24 frames, resolution 1920 × 1080 pixel full HD movie capture, the use of high-definition picture quality (1280 × 720 pixel resolution) and standard-definition (640 × 480 pixel resolution) is able to 60/50 frames per second shooting. the shooting and the general PAL video formats (resolution 720 × 576 pixel, 25 frames / sec)"

"In order to achieve the desired optical properties, EOS 7D uses the EOS-1D Mark III with the same size pentaprism. "
"Able to track moving objects in AI Servo AF has been a substantial evolution. Be able to correspond through a variety of sports and shooting scenes of new AI Servo AF algorithm to achieve high-precision focus on moving objects. Not only the distance between the targeted and Pishe Ti, but also be able to select “19-point AF” or “regional auto-focus”"
"Eyepiece optical components using a high-refraction glass, reduces the chromatic aberration production. In addition, the five-prism light injection and the injection plane using anti-reflective coating. Improved light transmittance, has been a bright viewfinder. The internal information viewfinder display back and thoroughly equipped with a new LCD panel constitutes a “smart information display optical viewfinder.” Apart from showing the 19 AF points, the grid can display on demand, spot metering circle, three-dimensional electronic level and so on."

"central 8 to the double cross, all 19 points cross"
sounds like 8 sensors for the center
" "regional auto focus"19 pairs were divided into five focus areas"
sounds like you can group sets of AF points to act together.
"three-dimensional electronic level " in the viewfinder"
could be handy for panoramas.
"metering sensor also has the detection of RGB"
maybe snow will be exposed as white & not gray.
"the 19 AF points correspond to a corresponding metering area"
about time.
"92 million" dot &new design
a better lcd with less reflections and glare.
"a higher photoelectric conversion efficiency of the new photodiode."
"the transistors within a pixel was modified to achieve a higher S / N (signal to noise) ratio."
less noise is always welcome, I just wish they were larger photo sites.
"1920 × 1080P 30/25/24"
should make lots of people happy provided they include full manual controls.
and weather sealing.
It definitely sounds tempting, if only it were FF.
I can't wait to see what the 1D4 and a possible 3D look like.

Since it has 2 digic IV it can drive 2 lots of 9 AF point arrays +1 to make it an odd number

Well I guess that will be for 3D and 1 series. However, it appears all 19 Af points are x-type to f/5.6 just like the 40D/50D, which is better than 1D(s) III, where all but the central point are x-type at f/2.8 or faster only.
