oblivion came out in 2006 i believe so it would be 5 years since then when it came out. The next elder scrolls game im guessing would be summerset isle since this is what we speculated for quite a while along with skyrim. Summerset isle would be cool but i think its too small for a massive game so it would be cool to have it in an expansion pack or something.
:facepalm:
Here is a map.

Compare, if you will, the size of Vvardenfell to that of Summerset Isle.
Or to Elsweyr. Or to the Black Marsh. Or to High Rock. Hell, to anywhere but Cyrodiil and Skyrim.
