I'm in the "it won't hurt" camp, how much will it help? Unsure, gut feel is not a lot but it'll have a positive effect. I don't think people will run out and buy a vita straight off the bat but it does improve the value proposition, so what I'd expect to see is no initial boost when the ps4 launches but a very gradual increase in the steady state sales as the ps4 install base grows. The tricky thing will be measuring that.
