This could possibly be changes to the Tutorial in general, or lay the groundwork for a offline experience of the game.
The Tutorial no longer has a 15 Minute Limit for Gameplay like the Hunt gamemode.
Now after Tutorial End, there is a Mission Tab where all of the objectives and their status are listed in order.
EDIT: Also, if City Hunter were to lose his Bio-Mask and complete the Tutorial, he roars in the ending cutscene.
