Wasn't Oblivion supposed to be the last Elder Scrolls, but then they decided to give them Skyrim?
I think that was just a rumour. I think maybe people thought that, because they had acquired the Fallout IP, that would take up all their time. However, I'm fairly sure they always intended to continue the Elder Scrolls series as well.
Several members of Bethesda have also said that they consider Fallout to be as important to them as TES is. Therefore, we could be potentially looking at 4 or 5 Fallout titles from them. One can only hope. :foodndrink:
