Well, I didn't see this coming....
... but I'm as happy as a Hell Talon on the tail of a one-winged Marauder!
Assuming this will be a miniatures game (as opposed to computer or card, which are possibilities, I guess), I'm thinking this will be to scale with AT18, and there will be an initial plastics release. (I think a new A.I. would fall in a flaming spiral if it were all-resin miniatures, although Shapeways stores, et al, would rejoice...)
Imperial and either Chaos or Ork seem very likely candidates for launch plastics.
Personally hoping this isn't 'Aeronautica Imperialis: The Horus Heresy' ! Air fleets of identical aircraft seems a bad choice. (Titanicus got away with it because the background and original AT completely justifies that decision.)
Does anyone have more info yet?
What do you hope to see in new A.I?
