I'm pretty sure the "Microsoft is aiming for more power!" rumor has been debunked already. Not that it can't happen, but there's no evidence either way, except Sony being the one who seems willing to bite the $500 bullet so far.
Besides, IBM supplied to MS a processor based on the Sony-co-developed Cell Broadband Engine for the X360 in the past. So it wouldn't beÂ unprecedented.
If I dint clarify that in the OP then its my mistake. I think is less than a rumor but more assumption. I believe MS cant compete with SONY in any way, so they will bite the money bullet to at least assure more power.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
