I feel it would be the final nail on the coffin of the desktop. i7s for laptops are beasts (i7-4800mq, a regular processor appears to be beating most high end desktops), so it only remains for a way to have a beast GPU on demand.
USB 3.0 is just a theoretical bandwidth that will allow devices you plug into the port the access to copy/read/write at 4.8GB/s. But there are no devices that you can by that will use that amount and of bandwidth. And nothing short of a SSD will even fill out the 480MB/s that USB 2.0 used. So my best guess is that the reason why they don't put USB 3.0 is to clog up RAM bandwidth with an unnecessary feed from the motherboard.
The i7-4800MQ is not a "normal" processor for a laptop. It is rare you see a quad core/i7 laptop that costs under the $1000 price tag. Plus you need to look at heat issues. They will not be able to fit a good GPU into laptop for quite some time, considering the TDPs of the chips, and even after they do there will still be a twenty times better one for Desktop PC's. Desktops will never die in the enthusiasts/workstation/server environment. You ma however see BGA Intel processors in 2015.
