Ultra Street Fighter IV will be playable at PAX East next weekend. You'll have to go to the Machinima booth to play it, as Capcom won't have a booth presence otherwise. Meanwhile over at the Twitch booth, you'll be able to watch pros compete in the Capcom Pro Tour.
While we're on the subject of Street Fighter, Virgin Gaming's Street Fighter Online Series kicks off on April 8. Players in North America, South America, and Europe will be able to participate in regional online tournaments, and the top 16 from each region will be awarded points towards the overall Capcom Pro Tour standings.
