If they take 10 more months to release Cata.. they will have a few million unhappy, very bored, players. 3.3 is the LAST "major" content patch for wrath. It will be out in a few weeks to a month tops. I'm not sure they will wait 10 months for the next major content ( Cata )

IF they do, I'm sure most of us will be doing other things ( not WoW ) They have not said anything about when Cata will be out. But i think its sooner than most think. We will see I guess!
