I got it from posts from con goers, Pyro and HiTech. (and via Skuzzy online)

"WG: Great. Let's get right to the subject that everyone's dying to hear about, Aces High II: Tour of Duty. First, how's the development going? Do you think you'll meet your original goal of a 3rd quarter of 2003 roll-out?
DA: We're just a touch behind on it, but we'll still make the 3rd quarter. Things are rolling right along; we're starting to get into the "finishing stages. We did the demo at the [Aces High 2003 Convention], and people got to see that there's a lot done there. It's really just the things the users sees [visually] to finish up on. The guts of it are complete.
WG: So the core of the game play, the mission theater venue, that has been pretty much set in stone?
DA: That's pretty much designed, yeah. I haven't actually started coding the Tour of Duty, that is, the mission theater part of [Aces High II] yet. That coding will actually start, post
shipping of the beta of Aces High: Classic. The reason for that is that the new engine just needs some time on it. I mean, it's a brand new graphics engine, and it hasn't been tested on a lot of platforms. You always run into weird idiosyncrasies and issues you have to catch. So it could be that we actually release Classic before Tour of Duty actually debuts. "
Perhaps I just didn't "read into" things more as others seem to have?
