I strongly suspect that Sneakyracer's summary will stand as the word:
"I handled the A7R with the metabones adapter and a Canon 24-70L and AF is slow. IMHO the A7R with the adapter is perfect for Landscape, Architecture or Macro users that mostly work with the camera on a tripod and manual focus using live view."
If you want the best AF then there is no alternative to a Canon body. It appears from the initial reviews though, that if you want the best sensor and do relatively static subjects the two A7s rule and at a relatively low price.
Seems to me that Canon's scope for introducing a high mpx 1D body with a huge price tag is now seriously limited. Whatever high mpx body Canon do release is going to have to be reasonably priced, else the studio/landscape/architecture/portrait/product types will just splash on an A7r and keep their existing glass, and keep $1000s of dollars in the bank. All of this with the best sensor on the market. Its a no brainer situation if the camera suits.

No company can be innovative in every aspect of the market. Canon is working in lots of areas to lead the market. Currently a group of camera users aren't happy with one aspect of a DSLR system, that doesn't mean canon is waiting in all areas.
There's a difference between "leading" and "being innovative."
I honestly don't see where Canon has been all that innovative in the past several years. (Maybe in the video market? Don't pay enough attention there to know.) As far as cameras, they make quality bodies with a good feature set, and there certainly have been refinements. But all companies do that. We could look to the 5D3 and say "well, they improved the autofocus over the 5D2." Yup, they did. But how is that innovative? We could say "well, they came out with a mirrorless camera system." And then we could look at other systems that were on the market at the time of its release and realize it was very lackluster by comparison (and that's not even taking into consideration of what's been released since then). We could say "well they came out with a white DSLR" but even that's not innovative because Pentax already did that a couple of years ago!

From the Metabones website: Only Canon-branded lenses introduced in or after 2006 are officially supported. Autofocus may be disabled for older Canon lenses and most third-party lenses, including most Sigma, Tamron and Tokina lenses and all Contax N lenses modified by Conurus.
Haven't seen anyone try the 200 1.8 on an NEX body and given the razor thin DOF and tricky AF conditions indoors, I would say that is a torture test.

What is innovative about the new Sony cameras? I can see how the sensors they developed are innovative and have drastic improvements over previous technology.

hmmmmm, okay...good to know. I read that too but thought they just didn't want to give any guarantees.

A new punky in town and the first FF cross platform device that mates with any available lenses

No the Metabones adapter will probably not support your old lens. So no AF for you. And it's not sure you will have aperture control either. It's not on his list for lenses that have been tested and works with the adapter. With AF or without AF.
And even if the AF worked it would be way too slow for shooting sport like you should do. Think of this camera+adapter as a MF camera for landscape and static subjects

Why is that innovative, they just slapped an existing sensor into a basically existing body and lens mount. Minor refinements to the NEX-7
And why no love for the Leica M? It can handle EF and a wide range of other lenses. MF with live view should be no problem.
Most see A7(r) in different view than you do That is why you keep go around defending Canon. Nothing wrong with Canon, you just make it worse.

Why did people have such little interest in the NEX-VG900? That was a FF E-mount camera with a Sony sensor. For MF landscape work it would've been a gem

I think they have been hamstrung by their antiquated steppers and the refusal to outsource for new ones and instead keep soldiering on while they developed better ones. Probably also did not have the talent to come up with improved DR etc. One problem Canon faces is that they have very few research scientists and nearly everyone is an engineer with no PhD and no fundamental understanding of real research. Obviously they can do research, but IMO they are top heavy with engineers.
wow interesting, I thought they might be rife with PhDs

The Leica M cannot handle lenses other than M mount with its rangefinder. And even other than Leica wide-angle M mount lenses (Zeiss, Voigtländer) are crippled by the absence of any of the necessary in-camera software correction.
Other than M-mount, like Leica R, or EF, you need to focus without rangefinder, which means with LiveView, except the Leica implementation only allows magnification of the centre of the image...
Whih is why I haven't heard of EF lenses mounted on the Leica M. But I would love to be wrong.

Exactly. Even the people that want such IQ are reticent to buy into other options with a superior sensor. Is there any wonder why Canon does not feel any pressure.
