There are some bigger games passing by at E3 for Vita that nobody is paying attention to though. The new Batman Arkham for instance (though it doesn't look as good as the previous titles), was briefly shown also as a Vita title, I think.
And yeah, Vita Killzone gives me a nice, warm feeling!
@patsu: I loved LBP's single player. There's one level in there that's better than any in LBP before it. Also there are no really frustrating bits in there. Bit short perhaps, but there are some really great user levels now too.
