In my idillyc world, yet still grounded on reality (or so I hope ), the sequence of module release should be something like this:
1st. CMCW Mad Wargames: An extension of the base game to add the year 1983 (together with winter textures) and the Archer Able exercises, together with the inclusion of both West and East German Armies. (The soviets during that year were convinced that the Americans were about to invade them, campaigns with the americans in the offensive would be an interisting change from the usually depicted soviet invasion)
2nd. CMCW Race to the Wesser: A module depicting the push to the Wesser by the soviets. The british, belgians and dutch are included, together with the Poles.
3rd CMCW "Le Garde Sur Le Rhin" : The french are added, with campaigns depicting the defense of the Rhine by french forces in case of a effective Soviet bretrought. The rest of Warsaw Pact, together with Canada; are also added.
And with that, you have a hot war in 80s Germany mostly covered. From there, you can go wherever you want. Extend the year coverage to the early 70s or late 80s, add the southern and asian fronts, do some Alt-history scenarios, etc.
