Why would Microsoft adopt Blu-Ray to replace DVD as the standard disc format? The only reason they would do so is to provide an option for playing Blu-Ray movies on the system, and I don't see a need for doing that. If anything, they would probably use the existing HD-DVD technology for it's games instead of paying Sony licensing costs per system to include Blu-Ray. They already have the technology, it's capacity is close to that of Blu-Ray, there are no licensing costs, and it's a possible (though minor) counter against piracy, since not many people have readers/writers. Someone please tell me if I'm totally wrong in thinking this.
