I'm still more interested in the 3DS.
In fact, I'll wait until Kojima Productions, Atlus, Capcom and Square Enix announces their games to get really interested. And hell! We still got a couple of good games to enjoy on the PSP for some time, there's no need to buy this thing day 1 IMO. There's no denying though that this year E3 is going to be pretty interesting.
By the way, the Uncharted game that they showed was a port or what?
