1) the power difference isn't big enough for it to have a meaningful impact, not gonna get into spec wars and I dunno why MS are getting into such heated talks about it but they're right about one thing, so far the Xbox One games and PS4 games don't look dramatically different from each other, far from it.
2) Price advantage, biggest reason Sony will dominate at least early on, if they have sense they will advertise it over Xbox One's high price tag.
3) No doubt PS4 will have an amazing diverse line up in the long run, but so far? It's poor and doesn't beat Xbox Ones, due to the sheer amount of games they've announced. (Launch line up is far is MS's favour when it comes to diversity.)
So yeah, PS4 will do great, but if they were price comparative he'd be talking out his ass.
