USB 3.0, Sata 6Gb/s, PCI.e 3.0 these are processor capabilities, but who will design how these technologies fit on to motherboards?[/citation]
Conventional form factors have their roots in the nearly 30 years old XT form-factor. There has not been much change in form factors aside from the IO-shield and ATX PSU. If you want breakthroughs in form factors, those will happen with non-standard/embedded form factors which is exactly what you have in smartphones, tablets, ultrabooks, laptops, raspberry-like devices, dongle-type form factors, etc.
The main reason the PC industry needed standard form factors was due to the need for multiple IO boards. With Broadwell, almost everything you need to produce a working computer is integrated on the CPU package/die so the only reason left to stick with standard form factors is convenience: no need to re-design PCB and case layouts, just use the stuff already in stock.
Personally, my ideal future form factor would be a mini-ITX like one that has a x16 connector as motherboard edge connector along the top so the GPU card sits in-plane with the motherboard. This would enable 2-3" thick pizza-box style PCs while still allowing full-length full-height double/triple-slot GPUs.
