New trademark details for an Xbox Series X logo have been spotted, with the filing date being recorded as 16 April. The new logo is surprisingly simple, featuring the word "SERIES" running vertically by the side of a large "X", which has been deliberately stylized in an incomplete form. It's not yet known if Microsoft will actually use the logo with the Xbox Series X console.
