Good RECENT RTS Game to play online?

The last two RTSs I've played online were C&C3 and World in Conflict.

Anyone recommend me a nice RTS I can play online against others? One that came our recently?

Company of Heroes, I highly recommendDoom_HellKnight

I've already played it. Not online though, it didn't look to fun online. I'm looking for a traditional type of RTS... like C&C, Starcraft, Warcraft, etc. Like, with building, an economy, etc.

Company of Heroes obviously.

Edit: was typing this when the thread had only one post. The original (OP).
