-Air marshall. Still a big mystery.
-SP career. I have no idea if there are any new features in this area, or just a 1:1 continuation of existing career mode.
-Fuel management. There have comments sprinkled here and there. It may be a feature that comes later, probably not with the official BP release.
-Tank crew and FC release news. TC campaign details.
-Moar 4K skin upgrades.
-Collector planes? It might be way too early for any details yet on the Yak9 and Hurricane. I think they said they would come early next year.
-BIG ANNOUNCEMENT OF NEXT MODULE. Probably will come as a separate announcement, not a DD. Either way we are getting close to it, and it's very exciting. I know some people will be disappointed because "You can please some of the people all of the time, you can please all of the people some of the time, but you can’t please all the people all of the time". However, those not getting the map/expansion they hoped for, remember that no matter where we go next the sim keeps getting better and better every patch and the core mechanics and feel will be there regardless. Just remember before BP was announced we all thought the Pacific was next, yet BP happened and I can't say i regret the change of plans.
Sorry for the long ramble!
