I'm not that impressed to be honest. Wii Music might be cool. Paper and Mario Galaxy I'm totally up for. I'll have to see Metroid before I buy it. The last too games looked good but were dull dull dull to play.
As for the DS, jesus - Phantom Hourglass and Mario vs Donkey 2(great).
Ninty needs to GIVE all their R&D to third parties by the end of the year. So there can be at least one good one..
