Yeah but why was it not even mentioned in the whole brand redesign ? Xbox is clearly NOT a windows branded product, it stands on its own and should have been part of the "New Microsoft" brand image.
I agree the Xbox brand should stand separate of Windows overall. The author did show an image of the Xbox + Kinekt at the beginning but focused on showing the new branding on a laptop later. Perhaps he simply ran out of time or thought it would be obvious that the same branding would be used?
