It seems that the guys from XboxZone.com.au have posted a video of the Street Fighter II presentation made last week in Australia. The link to it is here. If you listen carefully the presenter talks about how it's going to be one of the next three games to be released (We can only guess as to what the others will be, but my guess is two of Uno, Texas Hold'em, and Cloning Clyde). Not the best of quality recordings, but does show us what to expect.

UPDATE: there's also a video of the Cloning Clyde presentation here (Thanks qwerty)
