Offering the 28-135mm is probably just one of the kits that will be available - it's also Canon's way of moving stock.
There must be an enormous amount of 28-135 lenses in stock since they've been offering this kit with the 30D as well lately. It would seem to me that 28 mm just isn't wide enough on the APS-C body.
On the other hand, buyers of this lens also have a lens that they can use in the future when (if) they go full-frame.

So... if it's true that the 40D would have a sensor and or the other stuff it takes to produce a 14bit RAW image... What exactly does that do for IQ?
Yes, I'm wondering the same thing. Can someone explain how 14 bit will improve image quality... and if this will bring IQ close to the 5D?

14 bits would theoretically allow you to capture more detail in highlights (instead of being solid white) and in the dark shadows (i.e. increases dynamic range). AFAIK this would help with RAW, but you don't necessarily see the result in 8 bit jpeg.
There is an article from a Spanish site predicting the 40D features. I can make out most of them but I can't see any weather sealing but I don't read Spanish.
Can anyone who reads Spanish see anything about it in the article?
The increased number of bits / levels will not necessarily have any effect on dynamic range, although if it's a better sensor (than e.g. the 400D), that might.

I kind of thought that too, darn it.
The picture last week showed the possibility of sealing with the rings around the buttons, different flash head with apparent sealing, etc. I wonder why the Spanish site doesn't mention it.
Question about the 14 bits: does that mean a new sensor for sure? If so, that would probably mean less noise because of Digic III?

It would be a different sensor, but a new sensor and digic3 are not mutual requirements, although highly likely in order to hit 6.5FPS @14 bits. My gut feel is the reason the 30D had the same sensor as 20D was that they had R&D issues, and a new higher res sensor with adequate performance was not ready in time for the 30D's launch. I am hoping the sensor in the 40D is a leap forward wrt noise levels and dynamic range in a 10MP package.

but there is a mention of clogging your camera as fast as 1/8000th of a second (at least if you use babelfish to translate that is, haha).
i wouldn't read the weathseal not being there one way or the other. either trust the photos or wait.

Weather sealing isn't a big deal with me either but apparently it is with some people. I guess it would be comforting if caught out in the rain or in a heavy mist situation. I know I protect my 20D when any moisture mist/rain, etc. is present.
I used Google translation and it mentioned clogging too! I had in mind something thick pored into the camera and clogging the works!
Hopefully all of this will be answered in a week or so but I love the guessing!
If the sensor is somehow capable of more dynamic range... then 14bits should make it more useful then 12bits... but I would agree that 14bits by itself, is at best a minor help... but then I am admittedly not a expert.
In looking for information about how 14bit RAW data might have helped things... I came across what I find as interesting... this 'popphoto' review of the 1DMIII... In it they basically say that the in-camera JPEG processing of HIGH ISO shots produces images with better 'noise control' then RAW images processed in Digital Photo Professional... Which if true, makes me wonder why Canon would not offer the exact same noise reduction/processing in DPP that is done in the camera? Also... causes me to wonder in general... if DPP or any other RAW processing software is really capable of doing anything special with the extra 2 bits of RAW information?
Also... Since I really don't know anything about 'PopPhoto'... has anyone got any other recommended reading on the subject of 12bit vs 14bit RAW, particularly as it may directly related to Canon's RAW images/data?
DPP (at least the version I have) has no noise reduction, so of course that is true. You need to use 3rd party NR software to clean up the noise after import, which is also a necessary task even when using JPG's because in-camera NR isn't that strong. That's why it is so important not to do any sharpening in-camera for jpegs or during import from raw. The sharpening prior to NR will strengthen the noise, making it harder to remove.

Me neither. And to be honest a weatherproof body is little use without weatherproof lenses which pretty much all of mine aren't. My camera bags are all waterproof and thats where the camera is staying if its raining!
DPP has a prefences/setup menu panel that allows you to set the luminance/chroma noise reduction in coarse steps. That is the case with the latest version, don't know about earlier versions.

ahhhh, never noticed that before... I expected that to be in the toolbar or someplace logical....
