Please don't lump me in with the 'haters'. It's quite frustrating. I'm not lumping the 3DS in because that's suffering a similar issue over the next few months, but at least it's shown it's stable. Neither scenario is great, though. And those Vita games? None will push systems. Maybe a small boost for a week but that's it. Hopefully FFX will steer the ship right, though.
I apologize if I sounded too agressive. I just want to point out one thing : God Eater is a 500K+ seller in Japan so I do think it has a good chance to lift Vita a lot (more than FFX HD). And for the other games I reckon that quantity matters as well, libraries sell systems.
