Kotaku had an interview with Reggie Fils-Aime, Nintendo of America's president, and one of the things they chatted about is the next-generation Wii. He revealed the is supposedly far into the future, and that this console will be about more than just the addition of HD capability:
He said: "The fundamental issue in the logic flow is that — and this is what I'm hearing, whether it's from you or Geoff or Michael himself — is that, gosh it's such an opportunity to take HD capability and link it with the Wii. And what we have said, repeatedly, is that that's not the way we at Nintendo do things. The way we at Nintendo do things is, you know, when we will move to a new generation, it's because there are some fundamental things the [current] console cannot do. What that says is that simply the addition of HD capability will not be the next step for us. There will be more to it. There will be additional capability. There will be additional elements, and, given that, it is far into the future."
