AI War 6.0 and Ancient Shadows were largely done by Eldon Harris (in terms of raw components), and then assembled into actual ships by myself. We're doing much the same for the next AI War expansion, although this time Blue on our staff is doing the assembling of the assets and then adding her own touches (she's actually a true artist, unlike me).
In terms of Exodus, it's pretty well delayed indefinitely at this point, unfortunately.
