Tony, don't worry too much about it. Nintendo has stated that they expect almost all first-party games to be in widescreen, and it's looking that most third-party games are as well. I can at least confirm that Wii Sports, Zelda, and Rayman are all in widescreen.

That's all I was worried about when the N said that the Revolution wouldn't be high-def. I understood their philosophy, but I was tired of playing in 4:3 and it looks bad when stretched on a widescreen display. I had the component cable for the Gamecube, and it still looked terrible when stretched. IMO, every Wii game that I've played on a widescreen TV looks much better than every GC game I played on the same TV. And that's with the composite cables. I have the component cables but haven't tried them out yet...
