Honestly, I don't think they did. I expect, sometime in January '08, many publishers to actually start taking serious action regarding the shift in the marketplace. Throughout the industry there has been a tendency (and desire) to think of Wii as a 'fad', and that's only now, after 2 holidays, convincingly disprovable.
The money left on the table this year is going to make a lot of people (not just the GAF) very angry, and looking at how fragile a lot of franchises and publishers seem right now, they can't afford to let that happen again.
2008 looks to me like it could be one of the most interesting, surprising years in gaming history.
