It is tough, if you think about it, to have to decided on which should be done next. On the one hand, you have the badly needed remodel of more than a few planes, but on the other hand, you have the demand to add certain planes to make FSO and other special events, a lot better than they are with our current lineup, not to mention more historically accurate (I'm not gonna bother trying to factor in MA, though it is a major factor in itself as well). If you go all on remodel, you'll see more than a few complaints about not having specific ac that would enhance special events. If you go all for addition of ac, you will see the complaints about our current line up needing to be remodeled. They are having to balance the two while at the same time, pushing Aces High to a new level.
Let's see, they just did a remodel of the Mossy, added two tanks, brought back small hills and made a change to the dar system. Currently, they are in the process of updating the towns and fields, and adding a new manned gun. My guess is they will be adding either a bomber or an attack plane.
After this update, I would say that a remodel of either a fighter or a bomber (or maybe 1 of each), would come next. Those of you who have played AH since it was created, which plane has been in the line up the longest, that hasn't been updated and is quite popular? Chances are, they will be remodeling that.
