I will also buy this and happily forgo any more Canon DSLR purchases for some time. But, as mentioned above I will first wait and see how bad the color shift is. By the way, color shift can be fixed but it is really the smearing that is key. That can't be fixed. It would be prudent to wait and see bad or good edge performance is with wide lenses.
From what I have read the color shift problem is not likely to be a problem with regular canon lens eg TS17/TS24, but rather relates to leica m-mount lens wider than 35mm. The problem is that the light is coming in at too wide an angle on wide m mount lens because these lens are so close to the sensor.
So fingers crossed that the 7ar will work well with my TS17, TS24 which are canon mounts.
I would just forgo getting a wide Leica M mount because what's the point if the edges are smeared. Apparently this is also a problem in Leica M that is fixed in camera by software. So its possible that Sony has some king of smarts that would fix it with m-mount leica or ziess but I doubt it.
The Sony A7R use off-set microlenses to help alleviate this issue which plagues the NEX7. The off-set of the microlens changes according to it's position on the sensor. Will it be enough for Leica M lenses? Don't know and really don't care as I'll never be buying Leica M glass. Zeiss glass is rich enough for my taste.

In my opinion, taking a smaller, lighter-weight body and pairing it with a nice heavy EF lens just defeats the purpose. If anything it throws off the balance. In the end, what do you save? A few inches in your camera bag? So not interested for the time being.
Who said anything about weight?
It's a way for Canon lens owners to finally get high DR at low ISO (and more MP).

I can wait for Canon to match this. In fact a Canon mirrorless with the same specs would be great. Until then, my 5d3 will keep me happy enough. The landscape season is over until spring for this non snow lover anyway.
Yeah it's entering winter here soon so it's a bit late so I'll wait to see what Canon announces next year. However, I'm not so sure they will be popping out with a cam with better DR next spring and even if they do what if it is an $8000 1DsX or something? What if it is 5 years more? At least with this there is a side option, one I might end up going for 2nd quarter next year.

What's with all this hibernation in the winter. It's a great time of year for photography. Sunrise up here is at 7:30, sunset at 4:30. No getting up at 4:00am for the sunrise and watching the sunset at 11:00pm as I do in the summer.

+1. The issue mainly impacts wide rangefinder lenses, Canon wides should be fine.
The issue for rangefinder wides is the rear elment is so close to the sensor that the rays hit the sensor corners at an extreme angle causing the smearing or colour shift.
To give you an idea I have a Leica 21 SEM. The rear element of this lens is so close to the sensor that dust particles on the rear element can appear like dust spots in photos if the lens is stopped down!!
The A7R should be better as it has offset and gapless microlenses.
Interested, but I won't be an early upgrader. I am waiting for a few more reviews to come and hope that the price settles a bit, too. The Metabones adapter needed to make my Canon EF lenses work adds to the price of the A7R camera body.
Even I hoped earlier this year that Canon will announce a body to match the D800E, I am more convinced that this will take another year or so for them (especially not if rumors are true that they will come first with a high MP 1D series camera). And I question that the sensor will be a huge improvement of what is out there already and will come with a much steeper price tag. So yes, if no unforseen positive surprises happen by Canon, the A7R is top of my list.
The only downside for me is my now outdated Metabones EF-NEX ver2 adapter. I asked Metabones and it cannot be upgraded to ver3 So another 400 bucks to keep using my Canon glass. Ordinarily you would not think this would be an impediment but the new Zeiss glass is very tempting. But the 7r is going to find a home with me with or without Canon glass.

A nice Freudian slip there.
I never wanted a camera like this - would've rather upgraded to 1D Mark IV - but I have to admit, the A7 got me wondering again.
Given the less than stellar results I've gotten from using various lenses with adapters on different cameras, it's not something I'm likely to invest in. I would rather wait for Canon to introduce a new sensor (with no AA or Bayer filter), or just stick with my D800E and F-mount glass.

That's why I am planning to wait for more reviews first, too. I read good things about the Metabones adapter, but we need to see how it performs in combination with some EF lenses and the new A7(R) camera. If you already own a D800E camera, then there is no or only limited need for the A7R camera. The only advantage here would be reduction of camera weight.
If people upgrade to the A7(R) cameras, they likely come mostly from Canon or alternative lens shooters, less from Nikon.

True. If I had the D800E and some Nikon lenses, I wouldn't pay much attention to the A7R. I would probably just think it's a cool move by Sony, and thats that.

Or they might be Nikon users who want to use Canon lenses like the 17mm f4L TS-E and 24mm f3.5L II TS-E...
Agreed - even those are more limited in number I think.
Time will tell next year if this camera system is more a transition step to a new affordable Canon FF camera model or if it will be a more permanently established high MP FF system suitable for Canon lenses.

The crux of that will be the adapters... unfortunately the existing adapters don't offer very high quality or precision, and the companies that do have the wherewithal to make good adapters (i.e., Canon, Sony) have no motivation to do so.
If a company like Sigma really wanted to shake up the photography world, they would take a camera body like the A7r, drop in a full-frame Foveon sensor, and offer a choice or lens mounts (or interchangeable lens mounts)...

I have a Metabones adapter for my Fuji, and the fit is very sloppy... that level of quality wouldn't likely provide acceptable results with a high-resolution sensor and wide-angle lenses.
