Well if you want new planes, you'd better prepare yourself to wait quite a while. New planes/cockpits takes a lot of time to make and from what we know it seems like most of luthiers assets are working on the up coming sequel.
Have you tried any of the bombers? I know they might not seem as "fun" as the fighters but they will give you a nice feeling of satisfaction when you complete a successful bomb run. It's a different kind of fun.
