yeah. I hope they utilize the game-breaking nuclear feature demonstrated a while ago. It would also be cool to get a North Korean storyline. The devs could have fun with that.
I don't think it is gonna be very Germany-focused, even though they were the primary antagonist in the past two entries. It is nice to get a new series villain every once in a while.
Me personally, the Russia lore seems to be a decent new villain, assuming the devs listen to popular demand.
Taiwan also seems to be a promising setting for the game, although most theorize it is gonna take place in Ukraine, as the recently released Alpha version demonstrated.
