How will the diplomacy be handled? I've already heard that you will revamp it, and I wonder about the Interface. In the previous games you could only talk to one faction at a time, but I think in the ETW-era big conferences were very common. I'd love the idea of having everybody at the table, like in Vienna 1815. One could make a suggestion and the others could "think" about it and then accept it or make their own suggestion. This way multiple-state alliances could would be possible, like the various coalitions against Napoleon.
