Each new Xbox console is developed in Microsoft under a code name or project name before it is set for a sales name. With “Keystone”, the internal name could now have been given a name for either a MID gene console or even the next console generation. Where exactly Tero Alhonen discovered the entry “Xbox Keystone” is unclear. However, the find is interesting, but especially because the code names for the consoles Xbox ONE and Xbox Series X | S are specified directly with Durango and Scarlett. Whether it’s actually about the code name for a new Xbox console, still difficult to say. But probably we did not hear “Xbox Keystone” for the last time.
