The next theme after 1886?

So I am pretty sure people are wondering what will be the next theme? I think that in time,the doors are open to everything and I have pretty much worked to get like a new focus, new stories if I want and an outlook and everything without feeling any guilt I am leaving anything behind. I got to tell you that there are pretty good source materials from past efforts that I have never talked about that could become things. Right now, I want to focus on just doing things without a main theme besides the 1886. It will ultimately not be something that is light but something revolutionary, oh because those ancient computers stand for something indeed. Oh yea.
