IGN's got a nice list of
expected Wii launch titles.
To summarize (with publisher/developer info in parentheses):
Legend of Zelda: Twilight Princess (Nintendo; also a GameCube title)
Metroid Prime 3: Corruption (Nintendo/Retro Studios)
Wii Sports (Nintendo)
Red Steel (Ubisoft/Ubisoft Paris)
Tony Hawk's Downhill Jam (Activision/Toys for Bob)
Madden NFL 2007 (EA/EA Canada)
Dragon Quest Swords: The Masked Queen and the Tower of Mirros (Square Enix)
Super Monkey Ball: Banana Blitz (SEGA)
Metal Slug Anthology (SNK Playmore)
Trauma Center: Second Opinion (Atlus Games)
Elebits (Konami)
Marvel: Ultimate Alliance (Activision/TBA, Raven Software)
Blitz: The League (Midway)
Rayman Raving Rabbids (Ubisoft/Ubisoft Paris)
SpongeBob SquarePants: Creature from the Krusty Krab (THQ/Blitz Games)
Disney/Pixar's Cars (THQ/Rainbow Games, Kobalt)
What looks good to me: If it holds, it's a pretty good line-up. A Wii-exclusive Maio title would obviously have been nice here, but I'd rather have a great game than a rushed one, and LoZ should sell some units even though it's also a GC title. I speak heresy, but MP 3 is of almost no interest to me, though it's a good mature-ish title to have in the lineup, absolutely. Wii Sports will, I hope, be a pack-in--promises to be a good tech demo, if nothing else. A Wii-mote-savvy Madden will be huge if it plays right and, along with Blitz, could go a ways toward ensuring Wii has a more consistent stream of sports titles than the GC (though I couldn't care less, personally). If Ubi tunes up the controls for Red Steel, it should be awesome. Trauma Center (Wii-mote surgery!) is definitely intriguing, and I'm pumped for a new Monkey Ball, even though I'm mediocre at it. Overall, a nice range of genres and pretty good 3rd-party support.
What's missing: Would've loved to have seen Animal Crossing in here--the kind of game perfect for networked play--but I gather from IGN that it's barely begun. Except for Wii Sports, I don't actually see a lot on here that I think will automatically appeal to the nongamer. The forthcoming Wario would've been good, maybe, or (dare I say) even a Mario Party game. In short, I can't see a lot of games that my wife--who was surprisingly interested in getting a Wii--would really want to play, other than Wii Sports and maybe Monkey Ball. There's just not a lot of pick-up-and-play titles in here right now.
