With the recent mass defection from the HD-DVD camp to Sony's BluRay it has been only a matter of time before the other shoe dropped - hardware support. After the defections Toshiba started flogging their players for half what they were before Xmas, even with a bunch of movies thrown in for free, which was a very obvious sign of desperation. Sure enough, today Toshiba announced a halt of development of new HD-DVD hardware, and the other manufacturers can't be far behind. So, so long HD-DVD, it's been good.
One hidden boon of the announcement - HD-DVD players and discs should become very cheap as people start to off-load their gear to migrate to BluRay, and yes, I'm thinking of you, Serenity.
