The Xbox showcase is here! E3 is not titled so it does seem like its own thing set during E3 proper and it’ll be live starting at 10 am Pacific/1 PM Eastern on June 13th, 2021. As rumored it has been co-branded as a joint Xbox and Bethesda event. We will be covering it live on our YouTube channel at http://www.youtube.com/XboxEra from start to finish.
The banner used features Halo Spartans on top and the planet from the Starfield reveal on the bottom, seemingly promising both to be shown (with the former being a lock before).
