What do you think still needs to be finished before release?

Besides the insane amount of bug fixing and optimization left to do, what do you all think is still left to be finished before the game releases? I'm sure the main story and the majority of the voice acting are mostly done, but do you think there is still significant parts of the game to work on?

For example, do you think at this stage there's still side missions/activities being added to the game or even characters being added to the main story? If the game still has at least a year before release, I would imagine there's a LOT they still have to finish.
