Almost nothing is known about the game yet
According to The Verge, Microsoft will hold its next major games presentation on June 9th. It will show many important games for the company, including a new part of the Gears of War franchise, which is now simply called Gears.
Gears 6 (it is unknown if this is the final title) is being developed by The Coalition, the studio responsible for Gears of War 4 and Gears 5. Given the plot of these two parts, Gears 6 should be a direct continuation of their story.
A fairly well-known insider shinobi602 on the Resetera forum stated that the game will look so good that people are simply not ready for it. With this comment he responded to the mention of Senua's Saga: Hellblade II, which, judging by the screenshots and trailers, looks very, very impressive.
Shinobi602 previously leaked a lot of different information. For example, he talked about how Arkane had taken on a game based on the Blade franchise.
As for other games, Avowed, Indiana Jones and the Great Circle and the new Microsoft Flight Simulator 2024 are also expected to be shown at the same event.
