Don't think Uncharted will greatly grow this gen. Never managed 10m on PS3's userbase afterall.
Excluive wise, Gran Turismo and Halo are the only franchises capable on Xbox/Playstation side. WiiU .. well, the console has to hit at the minimum 16m with a game having over 60% attach rate ...
It'll likely be a multiplat on PS4 if I had to guess.
