Joe Olsen a developer whose company writes applications for the Surface said that the next version of Surface was already in the development stage.
Though Microsoft won't comment on a release date, the Surface 2 codenamed 'Second Light' will be build on the original model and have a second projector inside the table computer that can project images onto a layer above the surface of the screen. In effect, the device will be able to overlay secondary images above those on the screen - such as satellite imagery. The machine will also have infrared sensors that can interpret gestures and movements without having to touch the screen.
