So, because we have Worldhoppers like Hoid, Khriss, and Nazh, and I think that I've heard that era 4 will be more science fiction.
Brandon Sanderson
Yes, era 4 is science fiction.

So, will we ever have a chance to see characters from one world in the cosmere go to another world in the cosmere?

So, there's a couple of things that I need to explain to you guys in this one. First is that Mistborn, I pitched to my editor, way at the beginning, as a series where a fantasy world slowly became a science fiction world. So we would pass through a modern era, where things are like our world, and then we pass on to a science fiction era, because I'd never seen that done before. I'd never seen someone take epic fantasy and then build from the events in the epic fantasy, like religions and philosophies, and then tell another story set in a more modern and contemporary world. And then in the science fiction one, the magic will become the means by which space travel is possible. So we're in the middle of that. Wax and Wayne is an interim, I'm calling it era 2. There's an era 3 which is 1980s, cold war, spy thriller Mistborn. Then there is an era four, which is science fiction, unless I slip in a cyberpunk, near-future science fiction, which I might do. So there might be five, we'll see. I've warned people of that. The last Mistborn series, whichever era it ends up being, is the last thing of the cosmere chronologically. So, it's a long ways off. All the other series have to finish before I can do that.
The other thing that people have to understand is that all of these worlds are connected in something we call the cosmere. It is mostly, right now, just easter eggs. It's important to me that people don't go, "I can't read Mistborn until I've read Elantris," or whatever. No, each series is about that series. There's easter eggs connecting them but you don't need to know it. It's just fun to find out; you can find it all out after the fact.
Are we going to see people traveling between the planets? Yes, you will see space travel between the planets. You have seen it already. One of the stories in the anthology comes from that era, but it's on a planet that doesn't yet have space travel. Sixth of the Dusk takes place chronologically near-end of the cosmere sequence. So yes, you have seen it, and you will see more of it. In Sixth of the Dusk, there are ones they call the Ones Above who have visited and these are people from a planet that you have seen, I won't tell you who, who are visiting.
