Drawn to Life
Mario Paint II
SpongeBob (not a rumor, read interview w/ ceo)
De Blob
(activision, electronic arts, and take-two might notice games selling on Udraw and pony up a few of their own.)
Nintendo helped design the hardware for the Udraw, they want it to sell well to help increase the wii base. I can see them putting a couple games on Udraw, in 6 months, if Udraw is moving units........and the first obvious game would be Mario Paint....that game sold well for them.
