Fable II Main Quest Only 12 Hours Long

Joystiq brings word from Fable II's developers that the game's main quest is only 12 hours long, but a lot of this is made up by side-quests.
We had a lot of fun playing Fable 2 last night (more on that in a bit), so we were disappointed when we heard from several Lionhead staffers that the game's main story would take most around 12 hours to complete. It's not that we thought we were getting ripped off, after last night we just hoping the answer would be a little closer to a hojillion.

Also, keep in mind: That's just for the main story. That's not figuring in the time you'll spend gambling, romancing, trying to get fat and all the other side quests that make Fable so Fabley.
