Addition to the Call Of War set?

The Call Of war games are very enjoyable, and I was wondering if there is another one of the games aside WWI and WWII? And if not, what the possibilities are of there being another one? It may be a bit out there but it could be highly interesting to have a Korean war or Cold War version. Maybe even a stretch as far as a modern game, perhaps? Either way, thanks for reading my thoughts.~
