Nah. Even if the Wii U is more capable than the PS3 and 360, I'm sure a lot of developers will still release games for the first two and not the Wii U.
As a PS3/360 owner, even though there are some good exclusives for each platform, I'd say 90% of the time, when I go to the video games store, I'm deciding between the PS3 or 360 version of the exact same game. The last time I bought a newly released PS3 exclusive was when Uncharted 3 released. The last time I bought a new 360 exclusive was the Witcher 2 (and before that, Gears 3). So, for the most part, I have two consoles that offer almost the exact same experience. And I'm almost positve I've purchased around 50 titles this year (just a guess. I could be wrong)
With the Wii U, I don't think that will be the case. It may share some titles with the competition but I think that most of the time, when I buy a Wii U game, it will be very different than what the "HD Twins" offer. It's like how the Gamecube was considered very different from the Xbox and PS2. Almost equal in capability but still very different from its contemporaries.
