They didn't say much about it, but The Elder Scrolls 6 is happening.
There's not much more to it than that - Bethesda ended their E3 presser by announcing The Elder Scrolls 6. They didn't show us anything, but they want us to know that it's happening.
After years of enjoying Skyrim ports on every machine possible (something Bethesda joked about during their E3 presentation), we now have a new game to look forward to. It'll be a while off, by the sound of it, and we might not have more details anytime soon, but hey. It's something.
We'll update when and if we get more information, but for now, let's just bask in the glory of this announcement, thrown out right at the end of an extremely good E3 presentation.
