I can’t see the chimps allowing Larry to make official rules for other companies (they consider competition) to make such a thing. Just look what they did to triple A. Maybe they will put out some kind of expansion pack of there own later (doubtful). It would be cool to have official LH rules and new sculpts like heavy tanks and tech upgraded units etc. It would also be cool to include some logistic stuff like tankers, oil rigs, and merchant ships to protect. The new map for AA40 could be a corner stone for the future. The chimps should take advantage of it and produce their own expansion sets for AA40 as they do for their other games. If they don’t be assured someone will, but it won’t be endorsed by LH.
FMG is already working on new sculpts for AA games, but now with AA40 just around the corner they should IMO (unfortunately) :-( delay it so they can bring in more units that a larger map will allow for. Of coarse such a project takes a long time so FMG’s time table may fit this anyway as I have not followed their progress closely.
