Being a fan of both the RPG genre and MMOs as well, I'm actually happy to say no.
There are several reasons why not.
1) Blizzard (the company behind the Warcraft games) did their franchise wrong in their third installment of the Warcraft games. In this game, they explicitly copied another game in existence (Warlords: Battlecry) and changed the entire feel of the Warcraft series. From this point on, I was turned off by their Warcraft games, but I wasn't against second chances either.
2) Have you tried playing the demo? It's a whoppingly huge 4 gigabyte download! I never had a chance to try it because the download was too big, taking too much time for me to get ahold of it to even give it a once over.
3) I've heard the fan base to the point of no return - I've been turned off by the hype and the advertising. Good, they got their market, they don't need me.
4) Call me biased but, since I've been in the works on a truely original RPG experience that would blow WoW out of the water, I don't care much for these stereotypical and overused RPG concepts being wastefully tossed to us players like they're something new to talk about. It's all rehashed material to me. Meanwhile, since I don't have a piece of paper saying I know what I'm doing, I can't even get my foot in the door to a company to bring my game to the market. I'm all alone in my efforts, now for about 15 years - and for 15 years nothing even comes close to the depth in my game!!! :D
So, no, no WoW for me! Yay!!
