Like I already said, the v2.1 AVCHD could be out next week and the v2.5 could follow in a month or two. Neither would have the rounded corners. And then the v3.0 would come out probably after some of the 35mm projects come out - or possibly never, if Disney releases the originals on BD in good quality.
As to the foreign tracks for the AVCHD, I'm sure it wouldn't be a problem to provide them separately upon request but if you have the GOUT in your language, you should be able to just extract the audio from it and it should sync perfectly (unless it's PAL, then you'd have to do a 25fps -> 23,976fps conversion first).
@Joel: You should be looking for all of the things you said or anything else you may think is wrong - it's happened many times before that little details got missed and weren't discovered until after the release. For example, colors or brightness changing mid-shot (or sometimes on the last frame of a shot) and stuff like that.
