Will more factions happen?

This is more like a question, are more factions (italians, japanese, etc) planned? I have been reading and i know some people don't think there should be good since historically italians were not that good and japanese would not fit into the game but thats not the point i'm asking here, the thing is if there is any other expansion planned, or possible? Or the game will just stay as it is until a likely-ish coh3?

Thanks!

(I'm not saying the game NEEDS more factions, if it stays as it is it's ok, i'm just curious)
