Gears of War studio head Rod Fergusson got on stage at Microsoft's press conference to announce Gears of War 5, coming from The Coalition in 2019. The following trailer was surprisingly character-focused and combat-light, setting up a story focused on Kait, one of the squadmates introduced in Gears of War 4. 

The video shows off new wintry environments, melee combat with a giant mace, and new bio-machine enemy types that look vaguely Borg-esque. It's hard to tell from a single trailer, but Gears 5 seems to focus less on having a full squad at your side as you fight, and more on exploration.
