hardcoremore I just assumed 5 people with 100k/year, to at least manage to keep AIR compatible with latest iOS/Android requirements, and just keep Harman from pulling the plug.
Of course, I have absolutely no idea how Harman manages its business internally or its expectations.
EDIT: Last year Adobe pulled another "bad guy" move, pulling the plug on Adobe Muse (a software for creating websites without coding, which I really liked). There was even a petition made, signed by 5,881 so far, so there is at least an indication of an audience for that app. We don't have such an estimate for AIR.
