They won't be going backwards. All the stuff tied to the 3D shape (lift points on the wings, where the airflow is modeled, damage zones mapped out in 3D space, bullet hits here it's a gas tank, here it's a tire, etc) would no longer apply. Too much to do to reverse the change.
Unfortunately, knowing a lot of effort went into this end result, I'm not seeing HTC all that willing to double it to do it over again. they are probably remodeling the Ju88s or B26s by now (or fill in whatever model next in line for revamping)
P.S.... Is it me or is the dark grey ammo counter against a black text box against a nearly black cockpit EXTREMELY hard to see even in sunny conditions?! I'm not even at massive resolution which makes things look smaller. I'm running 1280x1024.
