Some of the first reviews and impressions are leaking in:
Zelda - Gamespy gives it a 5/5. All previews around the net have been overwhelmingly positive. Obviously the game to get.
SMB Banana Blitz - Newest EGM has a review. Scores 6, 6.5, 7. Single player is too hard, controls difficult, looks last gen, but party games are a good time.
DBZ Tenkachi - EGM 7, 6.5, 7. Interesting take on a fighting game, but learning curve is steep.
GT Series Pro also gets a quick mention for being total garbage in every way.
COD3 is also compared to the PS3 version, where they liked the new controls, but gave the ultimate nod to the PS3 version for having better graphics and online play.
The two maddens are also compared, with the Wii version coming out on top for superior controls.
IGN said a few words about Red Steel - the controls arent what they should be, turning requires too much effort, doesnt appear spectacular, but not a waste of money.
Zelda is a no brainer. Trauma Center was a great DS game, and being that its more of a port, I'm sure will be excellent as well. Rayman looks like fun. I'm more excited to play COD3 on the Wii for the controls, although missing online does suck. I've played excitetruck, and it's quite fun, but didnt get much time with it. Red Steel looks alright, but doesn't excite me all too much. Monkey Ball looks like a fun party game, but I can't say im surprised to find out its borderline impossible in single player.
