Last week, I reported on some evidence piling up that suggested Playstation All-Stars: Battle Royale was coming to the PS Vita, figuring that an official announcement would be made at E3. Well, during Sony's 2012 E3 Press Conference, that's exactly what happened. Not only will the game be available on both the PS3 and PS Vita, but it will also support Cross-Play, allowing gamers to play with or against each other regardless of the system they use. The E3 trailer also unveils two new heroes, Uncharted's Nathan Drake and BioShock's Big Daddy, joining the previously confirmed Kratos, Parappa, Fat Princess, Colonel Radec, Sweet Tooth, and Sly Cooper. The addition of Big Daddy is especially noteworthy, as that's not a Sony character, so the potential roster of all-stars is even larger than originally thought. No official release date has been mentioned, simply that it's scheduled for later this year.
