have a die shrink down from 45nm?
Probably not. I haven't heard any word on further development of the Cell BE-processor beyond the 45 nm node. Nor for its cousin, the PowerXCell 8i processor. Sony could probably enable the 8th core though, yields should have risen considerably since 2008.
Personally I would trust Google to consider user rights a little bit more, but the exploitation of such a system is damn scary.
So you'd rather trust a company who's business model is to sell information collected from and about you to who ever is willing to pay than a company with a reparation to not share any collected information about anything to anyone, no matter what the price?
