gtx 1080 and tripple 4K monitor support

Does anyone know if the gtx 1080 supports running 3 4K MST monitors? Right now, the gtx 9xx series graphics cards have 3 DP ports, but can only run two 4K MST monitors running in dp 1.2 mode. There’s something about the graphics architecture which only allows two 4K MST monitors to run. I can power 3 monitors in 4K SST mode but I only get 30Hz at 4K resolution.

With the new architecture in the gtx 1080, is this still the same problem? Or can a single gtx 1080 graphics card power 3 4K DP MST monitors all 3 displays running 4K resolution at 60Hz?
