Any good Massive, Multiplayer RTS

I am looking for a good RTS that has a WoW kind of play. What I mean by this is a RTS that you can play with 1,000's of other people at the same time in a strategy atmosphere. Anybody have any good ideas?

I don't know about thousands, but a good RTS game coming out is World In Conflict. I love the concept because there is no farming or mineral mining, just fighting. You should check it out.
