I have subscribe to their newsletter out of curiosity.
I have bought AF2 because of ORBX so called ""Project A" (you guys), but ORBX as been way to silent lately.
I'm sure we won't hear anything before they get their working fine in P3D V4.
My suggestion, you have enough planes, only an heli is missing.

Work on something else then the USA. It as been done. Austria with it's magical mountain is a good suggestion and close to Switzerland.
Most area with great mountain is a must.
