Very difficult to say.. There will be a great amount of releases still happening this year. But I would go for either Uncharted or Mafia 3 I guess.. Mafia 3 because I just really love that setting.
Though everything could change very fast.. Same with Battlefield One and even Call of Duty will both sell a ridiculous amount of copies. And both might just end quite high on the list.

It's still far too early in the year to decide that yet, but a lot of people are expecting Uncharted 4 or Doom to be a GotY
?
I would say Uncharted 4: A Thief's End.
