Intel unveiled its 8th generation Core processors earlier today, which will launch on laptops first. As part of the launch, Intel has produced a promotional video of what to expect from the next processors, which will bring quad-core chips more broadly to laptops. MSPoweruser has spotted that the video includes what appears to be a black Surface Book.

Microsoft currently manufactures a gray Surface Book, and the company hasn’t used black on its Surface line since the Surface Pro 2 nearly four years ago. The mysterious device in Intel’s video could be a marketing render, but it does include the exact same eject key found on the keyboard of the Surface Book and the unique fulcrum hinge that Microsoft uses on its laptop.
