HD-DVD is taking another jab at Blu-Ray with the announcement of Toshiba using HD-DVD drives in the Xbox 360. Unfortunately though, the initial release Xbox 360 s will have just standard DVD drives and the HD-DVD will be pushed into the system when they are ready. Will this hurt Microsoft s initial sale numbers? Only time will tell. This really is becoming a sick thunder dome battle between Microsoft and Sony for the best next-gen console and now the stakes will be even higher because the Playstation 3 will be using Blu-Ray.
