Zelda is the only game I'm in any rush to get for Wii this year. That kirby game looks fun. I was going to eventually pick up Epic Yarn, but this new one seems more my type of game, so I'm glad I held off.
Pikmin should be awesome, I can't believe it took them this long to make it. The game is simply tailor made for Wii controls. Little King's Story was a great game but I felt it could have been much improve if it had the pointer controls.
I might pick up Conduit 2, under the condition that the online is solid, hacker free, and the single player experience sees some major improvements. The controls were already solid, so not much change is needed there. I loved the customization from the first game, was really one of its saving graces.
Beyond that, I'm just going to wait it out until E3. I have a hunch that we are going to see an explosion of motion plus games at E3 as sort of a last hurrah for the Wii. I think Nintendo should really localize Zangeki. Looking at the Japanese footage, it seems like a really fun game and uses motion plus well. Maybe we'll see a ToG localization also.
Wii is far from done in terms of key games, it's just that we probably don't know most of them right now.
