Microsoft can use it and if they don't they are going to tank, they will have to pay Blu-Ray Association(I think Sony and Toshiba developed Blu-Ray, and a bunch of others financed it, the BRA is full of everyone that financed it, not sure...) Millions of dollars but they can handle it and Sony isn't the only one that will get paid,everyone in the BRA gets paid. Correct me if I'm wrong I am mostly talking out of my A$$. lol
