Well...Soon there will be as much as DCS products :
DCS : KA-50, A-10C, P-51 and FC3 (not full modules so i'll count it as one)
BST : MI-8, F-86, Huey (I won't count cobra as its not a done)
RRG : 1plane (don't remember wich one)
VEAO : HAWK
Leatherneck : mig-21
3rd parties are coming pretty hard and the amount of modules will increase by 66% after the summer :) (I just wish they were 80's, but thats me)
