Uncharted 3 to support offline Co-op?

According to Gamestop's listing of Uncharted 3: Drake's Deception, the game will support 1-3 players cooperatively online and 1-2 players offline. Could this game be receiving split-screen in addition to 3D, just like Killzone 3?

Also, it lists 3-player online co-op, suggesting the 3-player min-campaign mode from Uncharted 2 may be returning.
