I am not so cynical as to believe that the only good way to make combat or UI has already been invented and the only possible choice is to clone. Tanaka tried something different, but (in addition to his stupid design choices) he was undermined by his insistence on building the game around combating RMT (i.e. server-side UI). I think there's still room for a fresh battle system that isn't created with fatal design flaws from the start.
Again, I'm not a UI or battle designer, so I can't say exactly what 2.0 should be. I guess the best question to ask is, which post-WoW MMO has had the most sustained success, and what did that MMO do differently than WoW?
