I'm quite disappointed, and you'll never get another dollar from me.
Whilst I completely agree that the PS3 issue is inexcusable, and I feel for those suffering under it, I can't help but think most people issuing the threat of never buying another Bethesda game will probably cave in under the next games hype and buy it.
This is a software issue. PC gamers could have some claim to a hardware driver conflict, but the PS3 is, as has been said, a static unevolving platform.
Hopefully they can fix the problem for PS3 versions of the game. I doubt it is unfixable, but it might not be quick in coming (not what people want to hear but thats the likelihood).
