It’s a possibility, anyways, according to a slick find by the dudes at Gematsu. Although it’s hardly a confirmation, the online merchant Amazon France has a listing for Marvel vs. Capcom 3: Fate of Two Worlds in Vita format. Interesting, that one! If you’re planning on picking up a Vita when it launches, then just maybe you’ll be getting the opportunity to air-combo and X-factor and other junk, all while you’re riding the city bus!
You don’t take the bus? Alright, then just do it while driving. That should be fine.
There’s still no set release date for the PS Vita in North America, but you can expect it sometime early next year.

I definily buy this game for the vita its so cool, to bad the retail disc for the console version but i guess im still buying it because im a great fan of this games, hope capcom get as a DLC megaman X, cyclops, Venom and KEN.
