The Surface Pro 3 supposedly has a Thunderbolt or Thunderbolt variant where the power and Microsofts own dock plugs into. I would love to have an external GPU solution for my surface pro 3 and see if Ben can make an eGPU dock for the Surface Pro 3. If it could have a pcie slot and extra usb ports and ethernet that would be awesome. I know a lot of Surface Pro 3 Owners would like this solution and were saddened by the non traditional thunderbolt interface on the Surface Pro 3.
