I expect the new Call of Duty to boost PS4 more than XOne. I expect Uncharted 4's boost to match, if not out perform, Halo 5's boost. We barely know anything about 2016.
What makes you think Uncharted is going to out perform or even match Halo? To my knowledge, it's never happened. Halo is beyond anything Uncharted is in the US as a brand. Not only that, but the genre itself (FPS) is much more popular.
I don't think Xbone will ever get close the PS4, but I think Halo 5 is going to be bigger than any exclusive Sony has. Sony's strength is the numbers. They have more AAA games that people want. MS strength is in how the few games that they have, sell in ridiculous numbers.
