I wouldn't blame sony they made blu ray they have every right to have an exclusive license to it, because it's there product, why would they want to share their biggest success in years to microsoft especially when sales for the xbox360 outranked ps3 by miles, they need something behind their winning hand.

It wouldn't surprise me if they didn't give microsoft a license well at least until they were on the verge of a new format then they would give microsoft or the company in charge of the xbox some rights to blu ray as they release a playstation console on a new and better format wouldn't that be funny. I heard that there was a red ray showing it's head around somewhere whether that's another companies attempt at bluray or not would be interesting to know.
