No I do know.
It is honestly the biggest game of all time, admit it or not.
The only thing that will kill it is it's self/Blizzard replacing/shutting it down.
Look at Everquest...it might have lost 80% of its players, but it is still alive and kicking...in fact more then most MMO's. It isn't doing as well as it did...but even the mighty WoW did NOT KILL IT.
Well, All hail the all knowing god. Tell me, my lord, when will it come out? No no, I must use my questions wisely... WHAT IS THE MEANING OF LIFE!?!?!?! /end sarcasm.
Besides, I'm not one to care whether or not if "kills" WoW, or "mortally wounds it". I just want to play. My statement you never know MEANS you never know what'll happen, unless you can predict the future, in that case, good for you.
