How do they have them mounted to the tripod That's one of my worries, I've heard the little plate on the Metabones isn't the greatest and mounting the camera only puts stress on the mount. It looks like they did something special in those shots.

Yupp, these pix are not very representative of Metabones and Canon lenses. There is some other weird adapter thrown into the mix; maybe a tilt/shift unit??

Well, I see the 17 TS-E and 24 TS-E II attached to a Metabones adapter, which is then attached to the camera. That all looks pretty much like I'd expect it to look. I'm talking about the plate below.

The pictures are showing the Canon 17mm and 24mm TS-E lenses mounted via Metabones adapter on the Sony A7R. There is nothing odd about them.
Regarding the Metabones tripod mount...It could be useful for more balance, but I found it a little narrow and perhaps not as stable as I would like.
However, from the pictures I've seen, the Sony A7R mount should be able to hold heavy lenses without any issues. Telephoto lenses should be used with their own dedicated tripod mount though.

I still have concerns about the actual battery life of the A7r. I frequently pan and stitch with 3-shot bracketing much of the time, so it's not unusual to shoot 2000 frames in a day. The 1Ds III or 5D III will capture that amount on one battery, though the 1Ds III can capture much more.

There is a vertical grip available for the A7r which will hold 2 more batteries.

Thanks Fred, I was talking about the plate it was on. It was hard to tell whether the Metabones was attached to it, the camera, or both.

Just looks a standard Manfrotto non-Arca style plate to me and the metabones is attached to the plate via it's little tripod collar.

The metabones is attached to the qr plate on the tripod head. It looks like the rear of the camera is floating just above the rear of the qr plate. If the tripod had an AS head the clamp would go on the megabones. I assume there will be proper Kirk as RRS L brackets soon enough.

Yes. It looks like the metabones foot is attached to the RC4 QR plate using a screw into the base of the metabones foot. The metabones foot istelf is an A-S plate, arranged "sideways" in comparison with normal expectations. It's just like the small A-S plates I use for my RX100 and X100s.
It looks like you'll need a height extender to get the base of the metabones foot up high enough to clear the 17/4L lens body (or 24/3.5L) above a normal-sized A-S QR base clamp. Regardless, it'll be nice to have a lens-mount system for shift (as opposed to camera body mount), so that you won't have to correct for parallax by moving the camera body in the opposite direction to the lens shift. With the metabones adapter tripod mount foot, the camera will shift, not the lens. That's nice. It'll work on my Mamiya/Mirex T-S lenses, too.

Thanks everyone, I'm so used to my RRS L brackets I went daft. Got the Metabones adapter tonight, right around when I typed my first reply. The foot on the Metabones is Arca style and fits in my clamp....but it's so narrow it kind of gives me the heebie jeebies. I guess I have to wait until I actually have the camera before I decide how well that is going to work, I'm so used to a bracket that fills the whole length of the clamp. That small foot does seem to be attached pretty well to the adapter, but it's going to take me a while to get used to the idea.
Also, without the electronic first curtain shutter on the a7R, I wonder if there would be less vibration with a good RRS L bracket anchoring the camera to the clamp. It would seem that you'd get minimal dampening mounting the adapter.
Good call on the adapter and panos, it will definitely them easier with the TS-E lenses. Kills two birds with one stone.

Well not so fast...The adapter tripod mount won't help avoid parallax error. The only benefit is better balance with heavier lenses.
I just did a little test with the Nex-7:
I attached the Canon 24 TS-E + Metabones adapter to the Nex-7 body.
Instead of using the adapter tripod mount, the camera base was mounted to the tripod. Unfortunately, this set-up was very unstable and wobble. I'm not sure how much better the new A7R tripod base is with or without the grip, but at least on the Nex-7, the Metabones tripod mount must be used for stability.
As Jim mentioned, the main problem with this adapter tripod mount is the height. When using it, the 17 & 24 TS-E can't be rotated and a grip for the A7R won't fit.
Perhaps Kirk or RSS will develop a custom L-bracket for the A7R and A7R with Grip so we can get better mount stability and forget about using the Metabones tripod mount...

You're right Fred, using the foot on the Metabones still means the lens moves when shifting. Not like the Hartblei collar that would allow the lens to stay fixed and just the camera moves. Would have been nice if that was an added bonus...

It's a $2.200 mirrorless FF (The worlds smallest and lightest) with high resolution and high dynamic range, that will accept your EF lenses through an adapter. It will also take lenses from Sony, Leica, and pretty much every other mount in existence.
You'll need an adapter for the EOS M as well, so what's the difference?
Adapted lenses aside, there will be 12 new lenses from Zeiss next year, especially designed for the A7 and A7R.
What is involved in 'especially designed' as compared to designed?

I would rather be interested in a real-life landscape shot (with some contrasty areas) comparing for example the 5D MkIII/II with a given lens (like the 24/3.5 TSE II) with the same aperture and ISO number with the A7R, Metabones adapter and same lens taking the exact same composition shortly after each other. Then comparing zoomed-in areas of both photos. This should tell us clearly about IQ and DR.
