Both systems have their problems - freezing issues, mostly - but I've not read of any PS3 owners who have had a console bricked by the game. If it does freeze, they just restart it and carry on.

To be honest, I think it's pot luck. I've been talking to a few 360 owners today who got the game last night, and they managed to play for a couple of hours before they went to bed, with no problems (well, a few framerate issues with the opening cutscenes, but that's about it).

You may be unlucky, you may not be.
