That board is actually an Élan Inverse relabeled for Burton because Mark is sponsored by big B. If you search Silk Road or any of the underground websites you can find it for sale on the black market.
A lot of people don't realize that Mark didnt even do his own riding in Sochi. If you look closely you can see that its a stunt rider wearing a similar helmet to his. A few famous riders did this at Sochi because the course was so bad and they didn't want to risk their careers.
The 2015 Burton Process is being manufactured back in the US this year at the Value City furniture factory in Hoboken.
