Has there ever been a Ghost Recon map that was in production but was dropped from any one of the games after before release?And if so why and any chance we could see some concept art?

You might get a better answer for the first GR from one of the artists who worked on it, but at his own forums.

They're probably all under NDA..Good luck..

Why would a NDA apply to games already released?

I don’t know if it’s the case in this specific instance but generally speaking it can happen for a multitude of reasons.
