I would rather like to see the next patch milestones tested and completed, have bugs being ironed out, balance improved and the game including its current dlcs polished before seeing another dlc published.
Can we please get all the DLC done first that are on the official roadmap?
Also: Cold War had been attempted once and failed.
Personally I do not see the appeal of a cold war scenario. It is basically sitting around, tech-rush the other side, build more nukes than the other side. The boredom is interrupted only by the now and then occuring surrogate war.
