This is a portion of a machine translated interview with 4gamer.net and Capcom…
4g: When speaking of fighting games, since you can’t (do something) without asking about hidden characters. How is that part of the game?
Capcom: This time we’ve got all characters available. Since we wanted to put a bang of all characters on the package, they’re all available with nobody hidden. There won’t be any character grudges.
Not really a big deal, in my opinion. If and when the game comes to the states, we are going to get new characters anyway!
