I don't know about you but I'd love to use reconnaissance platforms (MQ-1) on the new Afghanistan map! It'd make sense to incorporate it in the game now that we have the A-10C, Apache, Hornet and Vipers, F15E + C-130 in the pipeline (with possible AC-130 later). There is also talk of possibility of Clickable Tanks (in Russian)...
In an environment like Afghanistan, in 2000's era mission, I wouldn't expect to be fearing for Air Defense other than MANPADS, AAA on mountain sides. Since we will be getting new infantry models and animations in the future, wouldn't be fun for "Battlefield Commanders" to get video feed from above? + Buddy lasing or TOO Hellfire deliveries?
In the future we will get human air refueling capabilities from Airplane Simulation Company, EW and RF is getting some additional attention in the future. We have received new Datalink features too!
To conclude, I'd love to see more capabilities in the C4ISR-ish world added to DCS. LOTATC is great but it doesn't do it all
