Clearing up a misconception, the Activision/Blizzard deal is not about getting more exclusives. TL;DR: A/B deal is about increasing revenue for Xbox, not getting more exclusives. Games like COD or Diablo are never going to be exclusive because they make too much money on other platforms.

One of the concerns was the possibility that Call of Duty would not come out on PlayStation consoles, but Microsoft has guaranteed that the franchise will continue to be multiplatform. There will also be no exclusive content for Xbox, as confirmed by Phil Spencer, head of the Xbox division.
