[UPDATE: It appears that it was all a ruse, for the most part. While Monster Hunter 3 continues to exist on Play.com, the three missing games were all apparently just Photoshops, if NeoGAF is to be believed. Sigh.
The original story is below.]
Sony has been planning to announce some new titles for the Vita in the upcoming weeks. However, it seems someone has beaten them to the punch. Online retailer Play.com has let it slip that the PS Vita will be be getting a few hot titles in the coming months. The titles announced on the retail site are Monster Hunter 3 and Grand Theft Auto: Vice City Nights, along with Final Fantasy Type-O and Tales of Innocence R.
Most of these pages have been taken down. However, the Monster Hunter 3 listing can still be viewed.
