The 1.9 update for The Elder Scrolls V: Skyrim that hit Steam last month is now coming to consoles. The patch will sort of a few bugs and problems, but also add the new Legendary difficulty level.
The level system has also been given a revamp that allows for Legendary skills, something that pretty much removes the overall level cap.
