In an interview with Gematsu (via Gamepro), Street Fighter X Tekken producer Yoshinori Ono was asked if there would be any extra versions of this game. Ono responded by stating that if there’s to be any extra versions of the game, it would be handled similarly to Super Street Fighter IV: Arcade Edition instead of Super Street Fighter IV and Ultimate Marvel vs. Capcom 3. In other words, it’ll be done as a downloadable update for those who already have the game (and probably retail for those who don’t have it yet).
To put simply, you will risk being a sucker… again.
