The PS Vita for sure. I've been holding off on updating my PSP-1000 because the NGP looked so much better than the 3000s. Can't wait.
The Wii U on the other hand... not really interested at all. I'll stick to the Wii since the controllers were actually innovative and made certain games like Metroid awesome to play. Now it seems they are just grasping at straws for a way to be different.
