Considering the timeline between Morrowind-Oblivion-Skyrim...2016 maybe? Do you think they will wait for another 5 years or do you think there will be another TES with the next gen (let's say 2014).
2016 would be great, it would mean not a console launch title (those tend to be rushed and buggy) and not an end-of console cycle title either (those tend to svck visually being designed for old hardware). If both consoles come out in 2014, I guess 2016 would be great timing.
Won't be seeing another TES for a long time. I believe TES: O may delay its announcement as well. And Bethesda's focus on the Fallout franchise with Fallout 4. Definitely want some news on Fallout 4.
