There's not even a hint of MP fixes/features. That's ominous news for a 1st expansion, considering the history of the Civ franchise.
Civ3's 1st Expansion:
- Specifically added MP to a non-MP game
Civ4's 1st Expansion:
- MP-oriented bug fixes and features
Well with Steams ability to do small DLC/Patches, I would not expect to see MP fixes/features listed in an XP. As soon as you did that you would have people crying that they are making us pay for what should be free :-/
They have already said that Pitboss and the SDK are coming at a future date, it is reasonable to assume that they know the last MP patch did not fix all they thought it would and more are coming.
The good thing is that the money they get from an XP can be used to justify having programmers spend time on patches that are released in parallel.
