With the install bases of the next gen becoming greater, more dev. time, and more opportunity, I believe that Call of Duty will be around for some time. How much I dont know, but I dont believe that 2017 will be the last year we have heard from the FPS series.
For me though, I would bet the 'WildCard' the series can now devote more time into is eSports. Since the UK is already building arenas for said form of competition, and Call of Duty being quite popular over in the UK, along with continual increased viewership, I would say having something like eSports can further increase interest. How much remains to be seen, but if Black Ops 2 and Advanced Warfare were any form of indication, it seems that Treyarch and Sledgehammer have their bets on making the series as balanced as possible to not only invite enjoyment, but competition as well.
