Not much for this year to be honest.
Deathloop + DLC, some unnecessary remaster - Banjo/Gears Collection/Goldeneye, Grounded release, Forza reboot, Forza Horizon DLC and presumably some decent 3rd party gamepass day 1 games. Maybe they'll show Halo Forge and co-op but unless the BR mode that Certain Affinity are apparently working on is ready to show, I wouldn't be surprised if Halo Infinite skips completely. Think one of the announcements will be a shadow drop - either Grounded, Forza Horizon DLC or a surprise gamepass announcement (maybe Final Fantasy 7 Remake, Diablo 2 Remaster, Suicide Squad/Gotham Knights). Maybe State of Decay 3 is this year but I doubt it, since Starfield and Redfall were penned in.
For next year, could see them showing Starfield, Redfall, Avowed, one of Indiana Jones or Wolfenstein 3, Contraband, and then new IP from one of Coalition, InExile and Obsidian. Maybe Hellblade 2 but we did see gameplay not too long ago. Could see something from ID Software too, maybe Quake reboot.
Think Fable, Everwild, Outer Worlds 2 and Perfect Dark are all 2024/2025 so only expecting one of them to show, if any.
Not expecting Activision to show up. Only one that could be possible is Diablo 4.
