I'm more interesting in the fact that he is showing Halo 2 running on (what I'm guessing) is the microsoft surface. It seems like a strange choice to choose a game that is almost 10 years old unless he is hinting that Halo 2 Anniversary is also coming to PC?

Halo 2 was also the very first game to officially support the XInput API of the X360 controller on Windows, so he might be paying homage to it by showing that the first game running with the Xbox One controller is nothing else but Halo 2.
