Go here: Starfield

According to Todd Howard, "We have also been working on a brand new, next-generation single player game. But this one is in an all new epic franchise. Our first wholly original franchise in 25 years."

There has been a lot of rumors about this one, that it's possibly set in the Fallout universe, but by saying it's a "wholly original franchise" I think that would point to something completely different since Fallout was a purchased franchise not originally developed by Bethesda.

So, I guess just watch the trailer and enjoy until we hear more.

So many cool games! I'm gonna have to get me a clone.
