The Coalition’s level designer Benjamin Huyghe seems to hint something.
In 2024, there will be five years since the release of Gears 5 back in 2019. Since then, we haven’t gotten a single major Gears of War adventure from The Coalition, and the only release is the spin-off Gears Tactics (which was mainly developed by Splash Damage). The Coalition was also somewhat involved in the impressive The Matrix Awakens demo from 2021, but that is all.
This means Gears 6 shouldn’t be too far off, and fans on X seems to think its announcement is finally about to happen.
