It's too easy to be a critic on these boards. When I look back a couple of years and see how far AH has come with just the small crew they have, I am simply amazed. I'm in awe of their programming abilities and business sense.
Having said that, I do wish we'd get more information from them about what's coming. I feel involved with the game on a deeper level than just playing a few hours a week. I'm genuinely interested in what's in the works, how it will affect gameplay, plans for future aircraft, progress reports, etc. I think it'd be a great way to generate pertinent topics of discussion on this board. As it is now, the board generally seems to be whines about gameplay. That can't be too impressive to newcomers.
I think I'd strive for quarterly updates to the game version if it was me. If that's an overly aggressive pace for programming changes, every other version could be just new planes. Personally I'd rather get more new planes into the game ASAP - it'll help greatly with scenarios (TBM subbing for the "Kate" in Midway - blecchh!), and may help the CT and/or the Mission Theater become a more popular option.
Its been over 4 months now since 1.10 came out, and we've had only a very brief description of the changes for v1.11 several months ago, and a screenshots of 3 new vehicles.
Right now, AH is simply the best, but competitors are on the horizon, and oddly, I feel like I know more about what's coming in them than I do about what's coming in AH. It'll be interesting to see what happens in the next 6 months to a year.
