So far, I believe it will be the following for 2020 - 2021.

Edit: Just to clarify, I know some of these games will base on the regular xbox one as well.

Hell Blade 2

Halo Infinite

Forza Motorsport 8

Forza Horizon 5

Scorn

Next gen version of Minecraft (ray tracing and additional features)

Cuphead 2

Flight Simulator

Age of empires 4

Hellblade 2, 2021 will be 4 years since the original so I’m betting it’ll be ready by holiday 2021. Forza 8 will be a launch title and Horizon 5 will be 2021. Each team taking a extra year (usually they make bangers within 2 years so 3 years for each Forza?!?! Can’t wait to see what an extra year does for each.

I see Sea of Thieves, Minecraft, Gears 5 becoming upgraded launch titles. Maybe Psychonauts 2 Series X port. Halo Infinite, Gears Tactics, and Flight Simulator of course. Age of Empires 3 Remake and Age of Empires 4 possibly end of 2021. Compulsion is due for a new game, maybe fall 2021 for them. Grounded will also get a official release within the first year I’d say.

Pretty solid for year one 1st party. Everwild, Project Mara, Undead Labs Game, Obsidian, Playgrounds 2nd RPG studio, The Initiative will obviously be year 2 and onwards. Probably missing some games from the other studios and 3rd parties but that’s the general jist. 

Yeah, I can see everwild  being 2022. Forgot about flight simulator, should be a cool game to show off new graphics. The initiative is supposedly making a perfect dark game which has me excited.

Hopefully fable is real and coming out sometime around summer 2021,although that might be a bit early.

Halo Infinite
Halo Wars 3
Xbox IP smash Bros like game
Banjo Racing

Sea of Thieves Expansion

Diablo like game set in the Fable universe.
Throw in some already announced ones as well as a few unannounced.

I think Phil is going all out in the first 12 months.

"At last we will reveal ourselves. At last we shall have revenge."

Halo Infinite, FM8, Medium, Scorn, Hellblade 2, Flight Sim, Gears Tactics, Fable reboot(maybe), FH5, Grounded, Perfect dark reboot(maybe) and at least 1 or 2 games from XGS Publishing.

Are AoE games even confirmed for XBSX?

Considering MS strategy on crossgen I wouldn't bet on any game being console exclusive on release or first year of the XSX.

If you are talking about the MS Studios games that will be released on XSX from Nov 2020 to Dec 2021 them there is a thread made by @Pok87 that have the list of studios, last released game, and expected next game that should release on XSX.

Halo Infinite (day one GamePass)
Forza Motorsports 8 (day one GamePass)
The Ascent
Second Extinction
Medium (day one GamePass)
Scorn (day one GamePass)
Call of the Sea (day one GamePass)
Hellblade 2 (day one GamePass)
Gears Tactics (day one GamePass)
Flight Sim (day one GamePass)

Obviously there will be others, and there will surely be XSX upgrades for existing titles like Sea of Thieves, Gears 5 is already confirmed, Wasteland, Psychonauts, etc and of course those will all be day one GamePass as well. Seems they have a very strong lineup for launch and insane value for GamePass subscribers. A stark contrast to the Xbone launch.

At launch for Xbone you were paying more for weaker hardware and a pretty meh launch lineup and first year of exclusives. For XSX you'll pay probably the same price for the most powerful console ever plus thanks to GamePass you can have tons of content day one with your console for dirt cheap.
