They called it off because WB stabbed them in the back. HD DVD will launch sub $100 players that will no doubt get the attention of Walmart. Don't forget that Walmart can twist the arms of studios because they are 40% of DVD sales!!!! Amazon is 3rd behind BB in total DVD sales and they aren't going to drop HD DVD. We'll be here for a long while. Walmart loves cheap, and don't forget the Chinese adopted a format that is almost identical to HD DVD so even thought they are slow to get it out there when it does cheap players will flood markets all over the world.
What's the point of continuing to push a format when there's no more content?
