The Wii doesn't support DVD playback. Its a unique phenomenon that almost defies being lumped in with the HD consoles. The other machines are living room devices with titanic amounts of rich content available from a zillion sources, whereas the Wii has a few games.
I'm going to go out on a limb here and say that the only reason the 360 and the PS3 have not done as well as the Wii thusfar, is that the market is already saturated with DVD players (a great many of them being PS2s). I hate to lump myself in with the "Wii is a fad" crowd, because I *don't* think the Wii is a fad... that would be like calling gaming a fad, which it sure isn't! It's obviously a market growing by leaps and bounds, and the Wii is certainly the market leader in many regards.
Yet... I don't believe it will never reach PS2 status. It will never tromp the competition like the PS2 did. In a sense, the PS2 occupied a unique slot in console history as well -- an early (meaning it beat the XBox out the door, and DVDs were quite new at the time), relatively inexpensive console & DVD player, on the verge of DVDs becoming the uber medium.
