Xbox has applied for a trademark for the Xbox Series X logo. It's not yet certain whether this is the official logo.
Microsoft filed a trademark application for the Xbox Series X in mid-April, including a logo for the new console. The logo consists of a stylized X and the word “Series”. Reddit users first discovered the trademark application.
The application also included a huge list for which this logo could be used, including on game consoles, controllers, posters, bags, mugs and clothing. Microsoft has written down a large amount of products so that they can use the logo for different purposes. This logo may appear on the packaging of the next-gen Xbox. However, it is not certain that this will be the final logo. Companies often submit multiple versions of logos that are not used.
