I'm going to say PS3. I think the only way 360 will win is if the PS3 was as under-supplied as seems indicated in retail musing treads here and abroad.
I also think that given these black Friday results, MS should have a pretty good understanding on whether or not a price cut for the 360 will be needed within the next few months. I must say, the PS3 has found a sweet spot in pricing right now.
