I think both will struggle under the release of other big AAA titles, especially X1 with Halo 5.
Uncharted has the best chance of doing well due to new PS owners buying the game, it releasing before most major games, having the Uncharted 4mp, and it being a refresher before Uncharted as a franchise comes to an end.
In addition, I think Sony will bundle the game to increase the anticipation for uncharted 4.
Also, one is a platform only exclusive and the other is timed.
