It appears that HD-DVD will win the high-def media format war, if history is anything to go by.

History lesson: In the 1980's Sony's Betamax tape standard lost out to JVC's competing and technically inferior VHS tape standard primarily due to the adult entertainment industry's backing of the latter's lower production and media & equipment costs.

While Las Vegas's played host to 2007's Consumer Electronics Show (CES), down the street was the adult entertainment industry's annual convention where many studios announced support for the more affordable of the two new high-definition media standards: Microsoft's HD-DVD. While Sony's Blu-Ray is admittedly a superior technology, as Betamax was versus VHS, it is the media costs, production costs, playback-equipment costs and popularity of the players (in part due to Microsoft's XBox360's popularity, which has a HD-DVD player available for it, versus Sony's Playstation 3 with its Blu-Ray player) that has sold them.
