Slightly worrying. I had a quick read through some of the threads you linked to and it seems there is a lot of conflicting information.

Some are saying it is the game bricking the PS3 due to a conflict with firmware 2. Others are saying it is only effecting the 60GB version of the PS3, while others are saying it has nothing to do with the game and is just a faulty batch of PS3 PSUs and the game pushes the system enough to stretch these PSUs over their limit and the system shuts down to protect itself.

But no one yet knows for sure. Someone even said the game is doing similar things to PCs and Xbox 360s, which I find very hard to believe. Especially to PCs.
