If I'm not mistaken though you are talking about the way the ac looks superficially in the game and I would argue that, that is not as important as filling the huge gap the f4fs represent right now.
I would argue that at this point, looks and consistency in airframe modeling is more important. New guys find the game, try it out...like the new models and cool stuff, jump in some of the older planes and puke in their mouths a little. They might not quit over it, but I would say it leaves them wondering what else is wrong.
While I agree there are gaps in planesets, efforts should be concentrated on getting all objects we have now levelset so the new stuff can start coming faster as HTC can stop splitting time between updating old stuff and adding new stuff.
