Like MUGEN said, CRAPcom and Square-Enix are the shitheads here... I think it must be because the 3ds is closest to mobile market in terms of development budget and time.. is cheaper to develop a high end game on the 3ds hardware, meanwhile the Vita is closest to PS3...
I can't complain about SEGA's support, except for the localizations, the same with NamcoBandai, Konami Is lacking a lot on Vita, but haven't released any major game on 3ds too except for a MGS3 port and the mirror of fate castlevania that lost exclusivity already...
I think there will be a slow shift of development from PS3 to PSVita, if the PS4 make it big,in one year or a little more Vita should be the target of mid budget development.. The Mobile market is progressing in that direction too, so is a matter of time when We see major projects multiplatform between Vita and mobile...
The problem is... that Vita will have games, but NOT THE GAME, that make selll the console enough to interest big house to develop major projects in exclusive... So in the worst case, Vita will become the Best Multiplatform Handheld of the Story... withnsome great first party exclsuives...
