OK finally, the list is obviously inaccurate and also missing games, but I included games that were already announced and that may appear. Any wrong or missing info will be appreciated.

DQX @ E3? E3 2012 perhaps.

That list is Amazing!

konami/sega shoud have that safari game also atlus probably will show Trauma Center 3 for the wii. also ther should be other games from preTGS conference Tact of Magic, Cosmic Walker, Endless Ocean 2, Line Attack Heroes, Demonic Slash

Natsume's E3 lineup is(what they confirmed):

Animal Kingdom: Wildlife Expedition
Harvest Moon: Animal Parade
Reel Fishing: Angler's Dream
Harvest Moon: My Little Shop (WiiWare)

Is Wii get Huge real or a joke?

oh and Disney will have probably Spectrobes WII game
Activision line-up is full of heroes - now if Tony Hawk game would have Ride Hero subtitle...

Is THQ going to be showing their "Biggest Loser" game for Wii? I just read about it today, so it might show up at e3

I thought UBI dropped publishing NMH?

Majesco's platformer looks fairly promising.

Seems to be fairly complete, aside from the secret Bethesda project and Capcom's secret game (presumed to be Wii, but not known)
