Last month, Sony confirmed the development of its Super Smash Bros.-inspired brawler, PlayStation All-Stars: Battle Royale. Based on a recent domain registration by Sony, it seems the game may find its way onto Sony's latest portable, the PS Vita. BattleRoyalTheGameVita.com and BattleRoyaleTheGameVita.com were apparently registered by Sony on May 24. This is after a sound designer for Sony updated his LinkedIn profile last week to include his current work on the game, listing it as a "PS3, Vita" title. With E3 looming just a week away, it's likely we'll get an official announcement then.
