Ever played Company of Heroes? Extensive use of AI interaction with the environment and a large emphasis on realism when it comes to cover, unit behaviour and ballistics. That, for me, is new gen RTS (though I wont rule out SC2 yet, weve still only seen what, ~5-6 minutes of gameplay?). Ever since TA this whole rock-paper-scissors principle has felt kinda... old. That said, I see RPS-style having it's perks as well, though I tend to lean more towards unpredictable and IMO more realistic battles.
