Love it or hate it, Call of Duty is one of (if not the) defining video game franchises of the 21st century. Well appreciated in its original form as one of many WWII-era first person shooters, the series catapulted to prominence with the (then) controversial decision to set the fourth main title in the present-day War on Terror with Modern Warfare. The game was a smash hit that cemented online-multiplayer military shooters as the definative trend in Western mainstream gaming and Activision's yearly COD update as the gold standard (in terms of sales) of the genre.
This being the traditional time of year for it, it's unsurprising that Infinity Ward would slate a major announcement regarding its popular game series. But some are now speculating that the developer could be poised to reveal the biggest evolution for the franchise in some time.
While Call of Duty remains comfortably well positioned in the market, the rapidly changing nature of console gaming has led to radical redefinitions in the genre in recent years. Most notably, the rising popularity of so-called "Persistent World Shooters" like Destiny and Tom Clancy's The Division -- which merge online-shooter gameplay with MMORPG open/expanding world content in the mold of World of Warcraft and its descendants -- have led many to speculate that the COD franchise may opt to itself follow that path.
