It is very likely that if a new Wii were to be released with 1080i or 720p resolutions, then we would have to buy the whole thing, much like the DS and DS lite scenario. That being said, however, it wouldn't surprise me if they did in fact release a new and improved Wii with a more powerful CPU/Video card in a couple of years, when HDTV is more prevalent in homes and more affordable. But they might alienate their own market since the Wii has been quite successful so far, so Nintendo might wait until the next generation to include HD support.
I guess my point is, no one knows except Nintendo. All we can do is wait and see.
