From an interview recently:
What do you guys think, am I being too optimistic in expecting this to ship at the same as BNW? It's been a long wait already....
Kate Distler (2K Community Team): .... Dennis, what can you tell us about multiplayer?
Dennis Shirk (Senior Producer, Firaxis Games): Well, we've got a full multiplayer team for this expansion, which is really nice, and they attacked a few different options. We've done a lot of polish, a lot of bugfixing. We've got some new turn modes. We've got an observer mode so you can go in and watch a game. We've got sequential turn mode. We've got a hybrid mode that actually lets you all play at the same time but when combat occurs and stuff like that it actually switches to turn mode and then goes back to regular at-the-same-time mode after it's done. And, obviously, the long, long awaited Pitboss. So there's a lot of great things that are coming out. And it's not just for Brave New World, those are going to be patched into all versions of the game, whether it's base game, Gods & Kings or Brave New World, it's coming out for all of them.
