I believe what Commie is saying is that some to most of the IA stuff (which I personally know nothing about on any level) will be used, but the factions themselves will be re-flavored to fit into the Red Wars narrative we have created in this little slice of paradise. New factions like san quevara will not be cut, the America side of the map will just get bigger and bigger and the geography of Calardia as a whole might get ret-cond to make this cohesive. Right?
Also may not have spelled ret-con right
