With Morrowind there were two expansions and 8 official plugins. With Oblivion (if you count knights of the nine as an expansion) there were two expansions and 8 official plugins. Using this information will skyrim get the same or similar treatment. Will it have a total of 10 DLCs with 8 being minor and two major? Will it have more or less? Thoughts?

Officially, Knights of the Nine is not an expansion. I don't consider it to be an expansion either. Besides, I believe Bethesda have stated that they planned to released fewer, Fallout 3-size, DLCs for Skyrim.
