I can see this changing, either Metabones will or someone else will fill this rather large hole in demand for those who enjoy legacy lenses and Manual Focus.
Those members with the SB please keep the examples coming, I would really love to see come Contax and Olympus tests.
I for one am not even a potential customer for this until a "dumb" or at least less expensive version in EF or Nikon F comes along.
Seeing as I have the lightest/smallest FF DSLR (6D), the benefits of size alone aren't much for me to justify something like NEX-6 + SB, at least not yet.

Hopefully we'll see people start to develop Alpa adapters to those other mounts, to take advantage of the short flange distance.
Thanks for the heads up alwang.
I wasn't interested in the SB because of the steep price and I have no EF lenses, but I own a Macro Svitar 50 and also adapters for Alpa to M42 and Leica-R. In top of that, the price of the SB for Alpa is only $450 instead of $600 of the Canon EF version.
Now, I must find a cheap NEX-7..
PD. There are also adapters for Nikon and Exakta mount lenses on Alpa cameras. All these are old stock dating back to the sixties/seventies, made by Alpa themselves and, as you'd expect, built to Swiss standards of precision.

You should get a replacement alundeb.
How do you know that? The different lenses behave differently with the SB. Some of the lenses reach infinity focus earlier than normal (the 85 1.8 much earlier), some later.
@alwang I spoke to Metabones on the phone about how the Alpa mount is poised to become the new universal mount for its shortest flange distance, so why wouldn't Metabones take advantage of this by introducing its own line of X -> Alpa adapters? They explained to me that the Alpa mount does not have a wide-enough throat diameter, so we may run into issues with very fast lenses.

The infinity adjust feature is a clever idea.
Alpa's mount throat is wider than most of the others, except Canon EOS. Would that mean that using adapters for Nikon/Contax/Olympus etc. on the Canon EOS version of the SB, will be problematic also for fast lenses?.
I spent a few minutes adjusting my Leica R - NEX speed booster, and it is now super sharp at infinity. It took a 3/4 turn to get there with a new 70-180mm.
Two snapshots with the NEX 7, CV Ultron 40/2 SLII, SpeedBooster, to show examples of the rendering.
The package fits in my coat pocket. Very convenient, a Canon 6D camera with the CV 40 wouldn't do that.
Both are wide open or nearly wide open. (the last one was accidentaly stopped down to f/1.6)
Lens correction and normal processing applied.

I think my next lens buy will be a CV Ultron 40/2 SLII ! Thanks for posting - I hadn't even thought of that lens.
I concur CV 40mm is very good on SB. Corners are good when stopped down and the manual focus is how I like... CV 40mm looks to me usable as walkaround lens.
Olympus 21mm shows softness on extreme corners, otherwise not too bad. Maybe it is due to its size which is similar to CV 40mm pancake and also SB design. I don't know if anybody will try a CV 20mm. Vivek is saying Nikon 20mm was good on his trials.
I have to adjust my infinity on SB if it will improve as nex-6 was showing more in focus reds in the front then back of the scene at infinity. I will post my shots to my pbase acct but a few from my wifes acct that I took yesterday:
