I don't have a super-firm date yet, but we're looking for 1.0 sometime the week of the 26th. So, basically in about 2 weeks.
The game will not be "done" in the grand sense then any more than AI War is "done" now, three years after its 1.0 release -- we fully intend to keep evolving this game as long as there is enough player interest to support it. But the core of the game itself is getting pretty darn rock solid, we're working on a glut of new content as we speak, and players can easily get dozens of hours of playtime out of the existing version as it sits. Once we have the last of the new content and bugfixes/balance stuff worked out, that's what sounds like a solid 1.0 to me.
And then the day after 1.0, we just keep right on adding to the game the way we did the day before.
