This interview in no way confirms this. Geoff Keighly asks a general question of Sony studios like Guerilla, Santa Monica, Naughty Dog and someone else... and the guy sort of smile and says 'we'll have lots of studios make games'. He could easily have just been talking about say, Guerilla, who've confirmed they're working on KZ.
It could go either way, but I doubt ND have anything in the works at the moment given they're working on TLOU and probably UC4 - but maybe Uc4 will be a few years off and some of them will start on a Vita game.
Anyway, point is this interview is misquoted and you really can't read that much into it.
