Well the apple doesn't fall far from the tree. It was just last month we were finding about PlayStation All-Stars Battle Royale for PS3 through Sony-owned domain registrations, and now the Vita version has been outed in the same fashion. Twitter user Superannuation has discovered a block of domains with various combinations on the title and "Vita", including PlayStationAllStarsVita.com, PSAllStarsBattleRoyaleVita.com, and BattleRoyaleTheGameVita.com.
So, who's rooting for cross platform play with the PlayStation 3 version? My Super Smash Bros. lovin' self will be mighty jealous if that happens.
