Well, at GDC a new RTS was announced, called RUSE. Basically the game is based off of poker. You know some of the information about what the other person/team has, but not everything. What you need to do is trick the person in what your doing.
To do this, you are given whats called RUSE cards which are abilities which you can use to hide units or send fake units and various other things.
Little is know about the multi-player but it looks like it might be interesting.
I've been watching videos on Gametrailers and I have to say RUSE looks pretty good. The battles look epic with the battleships shelling the landing zones and Planes flying through Flak and AA fire. The whole RUSE system will be interesting to see in multiplayer. Could make for some very epic muliplayer matches.
