The PlayStation Vita version of Street Fighter X Tekken will have an exclusive "new feature" that Capcom is yet to reveal.
That's according to Capcom producer Yoshinori Ono, who told press last week that Sony and Capcom are working together on the feature, which he hopes to reveal at the Tokyo Game Show later this year.
He refrained from revealing any specifics, but reportedly hinted at the feature being something that lets you experience the full PlayStation family connected together.
Sounds like cross-platform multiplayer to us (as has already been confirmed for the WipEout 2048 on Vita and WipEout Fury on PS3.
