It's not like you don't have to pay $200.00 (damn near the price of a Wii) for the HD-DVD upgrade on the X-Box 360.
Besides they do that in Japan for the economy of space not for the technological advantage, they have very small homes/apartments and any amount of space they can save is at a premium.
I don't care so much I'll stick to my 3 other DVD players, (not including the PS2 and my computers) because I'd rather use something that was made to play just DVDs and not had it thrown in as an add-on.

If you are wondering why 3, One plays DIVX/XVID, One plays any region/disables macrovision and One is the first player I purchased a 5 disk Sony.
