The organizer replaced SSF4 with AE, that means you will see Umehara's Yun for the first time outside Japan at the event. If he joins Marvel vs. Capcom 3, too, then it'll be his first tournament ever for the game.
The first place of SSF4AE and MvC3 will receive $10,000 and $2,500 respectively.
Note that E3 is on June 7-9, and MadCatz will have a booth there, there's a chance that Umehara will be at E3, too. Google Maps said that the distance is 14.6 miles.
