Actually, all we have to do is wait on a "combo" deck to be developed.
Samsung has already promised one as early as this November (although I'd be *shocked* if it really showed up then.) :

A "combo" deck would play DVD, Blu-ray, and HD-DVD. (Presumably, it would also provide standard DVD upscaling to 1080i).
IMO, "combo" decks will be the standard DVD player by November 2008 and will cost less than $200.
The hardware manufacturers and the studios *should* have standardized around one optical HD format. It's shameful that they didn't. But these Combo players will eventually take the sting out of the whole mess.
