The Vita will be fine. It's doing pretty badly at the moment, but things will pick up once more games arrive and Sony cuts the price. It worked for the 3DS, it'll work for the Vita too.
I'm kind of biased when it comes to the PS3; I don't want it too fail, but I don't want it to do TOO well because I REALLY don't want to have to wait until 2016 for the PS4.
