Just lately, the USB Implementers Forum have called the USB 3.1 specification which allows for 10Gbps link speed over the cable. But, like with the previous USB standards, it requires both ends of the link to support this standard for the high data speed to occur but will support the gradual degradation that the USB standard is known for.
It is seen as a competitor to the Thunderbolt connection technology but can link to more than 6 devices downstream. Like other USB standards, this could also be seen as a cost-effective standard compared to Thunderbolt once it is mature and and there is a lot of chipset, operating system and peripheral support for it.
Personally I see the laptops and all-in-one computers gain real benefit from it with expansion modules (docking stations), external secondary storage especially external hard disks; and DisplayLink-capable display devices with high resolutions and other high capabilities being the target applications. The latter application will also tie in with the USB Power Delivery specification to allow a laptop to be powered by a larger external display or projector that has its own AC power supply thus providing for a single-cable “walk-up” display arrangement for work or play.
