Look at the DS for your answer. There was a game-delay there too once everyone realized that Nintendo had transmutated a hit where they were expecting only failure.
How long was the DS delay though? 1.5 years abouts? And that was on a handheld! The Wii...
Of course, we have our Spring rush of ports and quickly released titles(with SSX Blur, Godfather, Sonic, Medal of Honor, Mortal Kombat: Armageddon, etc.).... And we're gonna have a Summer when Space Station Tycoon, Alien Syndrome (a Gauntlet clone with more RPG elements), and No More Heroes is supposed to come out.
But I expect the Wii's heavy third party support materializing with releases in Fall 2007. That is, support that stemmed from developers seeing the Wii launch and rush ordering kits, or ordering kits a few months before (i.e. development starting late summer '06 or fall '06). These games will be led by such anticipated fall '07 releases as MySims, DDR Wii, Call of Duty 4 (hahaha), Madden 08, and other here-to-fore-kept-under wraps releases.
Then we'll see in '08 more titles arriving in the aftermath, especially titles that have just started development at Wii launch or in january or February... probably as direct result of the Wii launch and all this good press.
