If for some godly reason Project Versus J is announced only for PS3 ... I will send a brand new Vita to Namco Bandai's US headquarters, with a message that reads, "Do you eat shit?".
Of course that won't happen, because A) Project Versus J ain't being localized, and B) if it was I imagine Scamco being Scamco, will wait for long after the JPN release so that people can import the expensive version, and then double dip. At which point it could be revealed that the game is a turd so I wouldn't want it anyways.
Also, with them not interested in OP
W2 Vita we can also rule those Digimon World, and Idolm@ster trademarks as them sitting on more stuff because they can.
