Man, why can't Arkham Asylum be out for Wii... Looks great.
I think I'm going to pick up the Metroid Trime trilogy- a collection of all three games, all for the price of one, with revamped Wii controls. Normally I wouldn't ever rebuy a game I have, but these are three of my favourite games ever, and the only problem I have with the first two is that the Gamecube controls are nowhere near as good as the Wii ones for Prime 3.
And if it gets good reviews, I'll have to pick up NHL 2K10 for Wii, which is getting good pre-release press. Gotta love hockey games, and unfortunately, EA doesn't release for Wii (and the PC versions of their games kind of suck).
