In the most recent rumor and news, X Box Series X could be rebranding its consoles as the Sega Series X in japan. Now this would not be an actual merger of the brand but more of a partnership between the two brands.
Microsoft has tried and tried again to make the X-Box a strong contender of the japanese market against Sony and nintendo but have failed miserably in the gaming giants home terf. Microsoft is not looking for Sega hardware but merely the Sega brand name which was a huge leader in the video game market in the 90s.
