A few other 2013 releases that aren't yet listed with currently slated UK release date according to Shop To.
Lego Marvel Super Heroes - 21st June
Lego Legends of Chima - 21st June
Moto GP 2013 - 21st June
Nm just seen they're mentioned with a hell of a lot more games on the previous page :D
Vita has an epic lineup, it's like previous posters said, for a "gamer" it's awesome, it's just not got those games that make someone think "OMG MUST HAVE RIGHT NOW!"
I'm loving it as a base for indie gaming now though. They feel a lot more at home on the Vita than they do on PC/Mac. And gaming on iOS/Android is just ROFL GTFO! Unless you add a physical Bluetooth controller or whatever.
