To make the next version better, Hendo turned to Mr. Hawk himself. In concept images released for the new Hendo 2.0 hoverboard, it appears to be a thinner, sleeker model. More of board, less of a awkward hovering slab. We won't know the final design until October 21st. That date, by no coincidence, is also the date in the future Marty McFly travels to in Back To The Future Part 2.
