Yeah, I know here we have another "My friend works at..." but I think this sounds interesting. As always, take it with a grain of salt:

"I have some friends that work at the marketing team at Xbox and they told me that its gonna be a crazy E3. There are 3 big things that Xbox will show off besides the price, date, and lock hart ( coming 2021).

​

1. More Studios- They are going to talk about new japan beside the studio that they bought, don't know who it is but my friends hinted that is FromSoftware. Also, they are buying 2 more, one is from Poland(NOT CD PROJECT RED!) the other from Canada.
2. Exclusivity deals- they are going all-in with this one. They have the marketing and exclusive content from Rocksteady's new game. They also have exclusive content for Cyberpunk 2077 and announcing CDPR next game (Witcher Based). They are also reviling quantic dream's new game with no release date just teaser. That's all I know but they told me they're more than more deal going on with publishers such as Rockstar, Ubisoft, EA and a lot of indie studios.
3. Launch Titles- The 3 big ones are Halo Infinite, Forza Motorsport 8, and Perfect Dark Reboot(made by Rare and The Coalition) ALL COMING AT LAUNCH(Subject to change). Launch Window November-April 2021. Fable (Playground Games) House Of Thieves (Compulsion Game new IP inspired by uncharted and BioShock. Obsidian Entertainment next game (AAA Open world RPG) mix between Skyrim and The Outer Worlds with some new intonations been in development since 2016. That's all the first party now the 3rd party launch. Assassins Creed: Ragnarok February 14th, 2021. Rocksteady new game November 28th. Mafia IV March 3rd. and last but not least GTA VI April 2021. (ALL DATES ARE SUBJECT TO CHANGE!!!).

Take all of this with a grain of salt some of it may have been lost in translation meaning my friend could have misinformation but I trust them.
