All I can say is this:
Colossal Order has been super industrious to get the train rolling on their future expansion. They’ve customized this to a whole new level, placing this DLC on the highway to success. The flood of new users will be like rush hour in Hong Kong, and the decisions made are sure to appease the mobs and prevent riots. In short, it won’t be disastrous, but will be an event to behold in its full virtual reality. Be sure to weather the wait, because it’s worth it!
There are no clues in the above paragraph. Only an opinion of how awesome I think the next expansion is 😉
Oh And Zombies.
