A little early but from the announcements so far I would give it at least a 8. Mario Kart 3DS seems to be the key game for me to purchase the 3DS. Luigi's Mansion being announced made me very happy. Star Fox will probably be pretty nice on 3DS. Super Mario for 3DS dropping this holiday season. Looks like the 3DS is about to get full time support from Nintendo. They should have a good software lineup for the 3DS this holiday season.
The Wii U sounds pretty interesting. I wonder how much they are going to sell that controller for?
