This is not an official announcement of the console, but the signal for the industry is clear: Microsoft is preparing new hardware for next year.
It is worth noting that neither Xbox nor PlayStation has yet announced exact release dates for their new generations. AMD, as a key chip partner, confirmed that these plans are real. The industry is already discussing that Microsoft's next console may become a hybrid of a console and a PC, with an emphasis on the Windows ecosystem and access to different stores, not just its own.
The final details will have to wait, but given that the Xbox Series X was announced almost a year before release, the first teaser for the new console may appear at The Game Awards in December.
