The video goes through "common" controllers based on themes, whether it be colors, laser cut models or many themed game models (did you know that the Thief Sea swab is inspired by precious stone in the shop?). You will often know why Microsoft chose a particular material or visual element. However, the real highlights are the rarities. You can see the early game zebra stripes that Microsoft sends to developers (above), company-only, and custom-made models that don't sell like the one built for the late awesome Xbox Addict.
Part of this is a sales pitch for controllers that you can actually buy, but it's also a rare sight in the world of hardware design that often gets a short break. The weather is also quite appropriate. The Xbox One is clearly in its twilight season with Project Scarlett Xbox only a year away ̵
