Cata not coming out until dec or later would be a loss for Bliz, people are already leaving or letting their subs run out, due to lack of new content. Sorry, RS is ONE boss and that will not keep people happy any longer than..hmm..now? I'm already sick of it. Believe is or not.. they WANT you to keep paying and playing. SO if Cata is not ready to launch by Nov, at the very latest, they will pull some content out of their ass ( like they Did with Sunwell ) to keep us busy a little longer, the pre-cata patch will help.
