This is exactly the kind of thing Sony should be doing.
Build up that first party.
The problem is not that Sony doesn't have a first party portfolio on handhelds: on the PSP, they had Wipeout, ModNation Racers, God of War, LittleBigPlanet, Killzone, Pursuit Force, Syphon Filter, Invizimals, Gran Turismo, Patapon, and Locoroco to name a few- but that none of their first party games, especially on handhelds, move systems.
If it is, then the Vita will become a priority purchase for me, I'm afraid.Rumor says it is linked to Demon's Souls with the involvement of From, but to what extent is unknown.
