I don't believe for a second Sony is going to use any AMD CPU for its next console. It just makes not sense to use the Phenom 2 and even worse the power hungry huge Bulldozer. They are not going ARM as they are still trying to catch the crappy atom in processing power. The next Sony box will be some sort of IBM processor and AMD graphics chip. I don't think we will see much difference in the next gen boxes except which gimick they try to use to sell em.
