Rage much? Maybe you established something, but Bethesda has yet to officially announce that it doesn't matter what PS3 you're using. It may matter simply because the people playing on the slim PS3's have newer systems. So yes it may very well make a difference.
Guys it's ok, dragons are not flying backwards, there is no bugged quests, and there is no texture streaming issues. Bethesda hasn't officially announced them so it's not true. Remember when the game used to run like a charm and then Pete Hines "officially announced" that there was "occasional" lag affecting "some people" and we all started lagging after that? WTH dude Y U ANNOUNCE LAG?!
You're sad. It's been more then established, move along.
