Yes, good list. On top of that, I'd love DTC functionality.
This is my biggest one, though: Considering the C-130 is coming and some of the helicopters that are in DCS now (and those to come), adding search and rescue gameplay would bring a dimension to DCS that would make it pretty compelling, imo. I feel like the pieces are already in place for that to be amazing, at least in multiplayer. I know there are mods for it, but I'm talking solid functionality and gameplay.
Oh, and the CH-53.
