As more and more 60GB PS3's get clogged with dust they're overheating and killing themselves, YLOD and freezing issues are becoming a big problem as the 60GB's get older. The game is one of the most popular games out there and is being played for longer than most hence the corrolation with more consoles failing when playing it. I expect if you look on Microsofts forums there will be similar reports of it causing RROD on the 360 too.
