Wonder about vice-versa. I'd love to have the more detailed damage model from WWI in the other arenas. Which I thought was the plan to begin with. 
Saxman: We *have* a more detailed damage model than before. It has more elements on any given wing or fuselage that can be damaged without catastrophic loss. It will never resemble the WW1 arena, though. Those are unique to the design and materials used in WW1 aircraft, and do not apply to WW2 aircraft.
Per HTC comment, that kind of damage is only for WW1, and won't be seen in the main arenas.
