IGN has some more meat:

Interesting part (said by Anatoly Subbotin, 1C's PR manager according to IGN):
"Birds of Prey will use the flight models that were developed for the PC game, but almost everything else was rewritten from scratch from the consoles. Visually, this is a gorgeous game; aircraft are rendered in sharp detail, but even more impressive were the fully 3D landscapes below. There are thousands and thousands of 3D trees, roads, villages, landmarks, cities, rivers, and more. Then there's a new damage modeling system where your plane can get chewed up pretty badly, to the point that it has gaping holes in the wings and fuselage, and that will affect your aircraft's handling on the more realistic difficulty levels."
If they have not used code from SoW:BoB after hearing that - I'd be amazed... But I have been before
Why do a detailed damage model for an arcade game? Pearls before swine
