Personally, I think it's stupid for them to leave out DVD playback, considering their non-gamer strategy and the fact that the cost wouldn't not be that high for them to implement it. I need a new DVD player with progressive scan, and if I could get one when I buy a Wii...
so yeah, I hope they just throw it in as a firmware upgrade or something...
anyways, I don't think they'd release a special edition Wii whose sole extra feature is DVD playback. What's the pt, especially in Japan, where everyone and their mother already has a DVD player (or PS2)
