Upon seeing these clear photographs of what appear to be a physical model of the "Project Cafe" console from this "Innovation Reinvented" slide, we could react in two ways. First, the photographs could lend credence to the slide, suggesting that all of this is real and the Wii successor truly has the listed features and design.
Conversely, we could conclude that someone either built or made a convincing 3D model of the device based on that slide, thinking that the hours of labor required would be worth it when someone was maybe kind of fooled. As this is the course of events that would best justify our constant cynicism, it should be no surprise that it's the one toward which we're leaning.
