Not with the 3DS controlling the market now and I don't honestly believe Sony is interested in trying to save it here. Sony choices are 1) put some studios to work on Vita games and likely still watch it fail while taking away from PS4 development, or 2) put nearly all of your first party efforts (if not all) into making sure the PS4 crushes the competition and definitely makes Sony a bunch of money.
Hmm, how greatly does 3DS really affect the Vita?
I do agree, Sony is not interested. But I don't think they need to take all their studios. Give it a price cut and 3 notable games.
