When something is uber popular there will be those who "dont get it" or bash on said popular game for no real reason. I've been playing WoW for 6-7 months now and I have yet to hit 60.
Then again, I do have a life.
Every other MMO out there right now is dull and extremely boring. WoW is currently the MMO king whether one likes it or not. Will it be there forever? Doubtful, but so far nothing seems to challenge it.
Sure, Warhammer LOOKS cool, but it could easily end up being another Star Wars Galaxies. I'll be sticking with WoW for the simple reason being that it's been the only GOOD MMO I've played. FFXI sucks, Guild Wars bites ass, Star Wars Galaxies just needs to go away and City of Heroes is a total snooze fest.
WoW is epic, and I've yet to see more then one person wearing the same set of armor....
