HD-DVD is going to be the better bet right now and from what i see in the long run. Cost, Availability, Support... Sony alone is heading up Blu-Ray and unfortunately there are alot of technology companys going to HD-DVD... they are getting ready to roll out triple layer soon as well. PS3 is being used to try to push Blu-Ray into the mainstream, but i just don't see it happening... no games have been made on it as of yet to take advantage of it (if i'm not mistaken) and if it goes like the PSP propriatary media it will bomb... i read/heard companies are trying to get rid of their PSP movies and are no longer purchasing them b/c its a losing market.

ps. hd-dvd attachment is coming out for xbox for the x-mas season
