XBOX:
In fact, we've heard rumors that Microsoft could announce up to three Gears games, including a traditional sequel, a real-time strategy title in the style of Halo Wars and a battle royale game. Perhaps the franchise will get traction with the larger user base on Windows 10.
Playstation:
We've heard and read rumors about a handful of unannounced games, like sequels to Bloodborne and Horizon Zero Dawn, along with another remake of a PlayStation classic (maybe Syphon Filter) and an upgraded PlayStation VR headset. But with so many games to promote and ship in the next 12 months, and God of War DLC still a question mark, Sony will probably hold most major reveals for future events.
