One thing people don't take into account, is that Sony and MS know more about what each other are doing than any journalist, blogger or leaked. I'd say, talking big picture stuff, they'd know more about each others larger plans than most companies in possession of devkits from both/each of them. Not that they'd admit it in public, of course, or even at shareholder level - but in private meetings - absolutely.
