Wow. We're just so happy that people are liking the game. We're also happy that the reviews are coming out very positive so far. And, well, we're definitely happy with the sales. It's doing even better than Galactic Civilizations II did which was really well.
Here's our upcoming schedule:

Get a v1.03 update out
Make Demo
Start work on v1.04
We hope to get v1.03 out by the end of the month (no promises though). Ironclad (and Stardock) are pretty exhausted from the final weeks of effort and the first week of launch so resting will be done.
So think of v1.03 as a few key tweaks that you think would really make the game more enjoyable not just for you but other people.
Here's an example of things we're talking about right now:

Updated AI players
More Game Speed Options
More aggressive AI players replacing dropped players (i.e. active AI)
AI surrendering
Improvements to ICO
Unit cap increases
We have lots of ideas. But the key thing to remember, we want to get 1.03 out this month if possible. So sure, we can all imagine things like random events or fancier diplomacy or other things of that nature but those would take far too long to get into the game.
