I'm joining the Hard Freeze club.
Got my mbp 15" 2.2GHz march 8.
Have had 2 freezes so far, doing multicore rendering in After Effects CS5.
These have been hard frezees, meaning total lock-up, I was not even able to move the mouse.
I have since the installed iStat, and I've had my fans at 6200rpm on only 20-30% CPU load.
My temperature has peaked at 94c, but generally stays in the high 80's
I called Apple and asked for it to be returned, so the will pick it up one of the following days now, and I will get a refund.
Ironically, I'm going to buy it again, but I'm hoping to get a model without the problems.
I feel that, since this is not a problem that's affecting all new mbp's out there, I'd rather go for a new replacement than try and get this one "fixed". To me, it's broken, end of story. At this steep price, I'm not looking for a patch solution. I'm paying through the nose for a product I expect to work form the start.
