It seems Elder Scrolls 6 isn't going to happen until many years from now, especially because Howard hints that the technology to create what they have in mind doesn't even exist yet:
"I could sit here and explain the game to you, and you would say, 'That sounds like you don't even have the technology. How long is that going to take?' So it is something that's going to take a lot of time, what he have in mind for that game, and we actually have two other large projects we're also doing that are bigger than everything we've done. People will probably hear about those even before Elder Scrolls 6. That'll make sense many years from now.No details were revealed about the other two "very big projects", but Howard suggested "they're all a ways off, and we'll talk about it when we talk about it."
"We think very long term. We're not a developer that's going to rush something like this out," he continued. "When you think about what is the future of that kind of game, we have a pretty good idea of what that's going to be, and it's just going to take technology and time we don't necessarily have right now."
