Both my girlfriend and I play WoW (for the Alliance~!), and I currently have gotten into EVE (Caldari pride~!) online as well. I've already declined to renew my sub to warcraft, and it'll be ending on the 17th this month; EVE I'm keeping on simply to keep my skill training going.
Despite the 'addictiveness' of mmo's, I've always found I'll drop any of them at the drop of a hat for a good console game.
O cool I was a former alliance but I quit after I lost my job due to the fact that I was clocking in about 100 hours a week with wow and the fact that the monthly and new area fees were killing my savings account. The crazy thing is that it's been almost 2 years since then and I still get "withdraw" symptoms, which is pretty unreal.
Anyway, back to the topic, I would suggest, had hope that TES keeps being unique in the sense that it does not become a MMO since there are already so many fantasy MMO's out there. Also, I like how the story is more interesting and personalized, compared to MMO's, were you in one in thousands or millions so it makes the game more enjoyable. -_-
