Why should Sony switch to x64 architecture? For uses that don't require back compatibility with x64 and x86 legacy SW, it wastes for it silicon, electric and computing power and money. OTOH Power architecture is very advanced, efficient and scalable, each generation can give the designer not only a wide range of computing power and power consumption, but also the choice to achieve the desired computing power through few powerful cores, many lightweight cores, fewer running faster, more running slower, more powerful and complex cores running slower, simpler ones running fasters and various steps and combinations between the opposite choices. x86-x64 architecture can't even dream the flexibility and scalability of Power.
