No one has a first party to match Nintendo, they've just been at it the longest and rely on it the most. I don't think that means Sony's first party is 'dire', its pretty hard to argue it doesn't have a better first party launch lineup for Vita launch than Nintendo did at 3DS launch.
But what else is announced for Vita? It's got one of the most unappealing software line ups I've ever seen for a console. Before the 3DS even launched we knew about Mario Kart, Paper Mario, Kit Icarus etc.
that's something I noticed, I've see all the excitement and felt temptation but then I look at the games line up and only see one game I would buy, doesn't make sense not to wait for a price cut, by then it will have the stuff the wife likes too and she plays them more, far more.
