Though it promises a variety of features, Skylake is generating excitement mainly because it’s expected to reduce the need for power cords, display connectors and other peripheral cables. Skylake laptops can have wireless charging, and also carry display and data signals wirelessly, which could spell the end for HDMI, DisplayPort and even USB cables.
One of the premier features of Skylake is Wireless everything...
Wireless Charging, Wireless Displays, Wireless Storage, Wireless USB, Wireless networking, Wireless ..., Wireless, all Wireless.
So... the SP4 could ship with a wireless hub and No Ports of any kind, maybe it will even be waterproof but only the low end Core-M model the i5 and i7 will still need cooling vents. I don't see wireless cooling working yet.
