The franchises Bethesda has that I care about are Elder Scrolls, Dishonored, and Doom. While I'm sure they're working on an Elder Scrolls VI, I don't expect to see it for a while. I suspect they're taking a bit of a breather period from Dishonored considering 2 and Death of the Outsider's relatively lackluster sales performances. Doom however, I would be somewhat surprised to not see something soon.
