Knowing what we know, I'll still go with XOne and Halo 5 at #1.
But there is a small possibility that PS4 takes the win, and an even smaller possibility that Assassin's Creed will be #1 (extra platform, 4 extra days, strong 2nd week...).
Either way it will be very interesting to read this in about 12 hours.
