Sony announced localization of 3 new Vita games today:
Soul Sacrifice Delta - May 13
The other 2 are slated for this year but no dates given yet:
Freedom Wars
Oreshika: Tainted Bloodlines (known as Over My Dead Body 2 in Japan)
Plus it looks like Tales of Hearts is getting localized! Gamestop had a preorder page up for it briefly today then took it down - my guess is they jumped the gun on Namco's announcement. ;) Shaping up to be an awesome year for the Vita! ;D
