New specification promises 10 Gbps
We don’t think that many people were complaining about the existing speeds delivered by USB 3.0, but performance about to get even better. The USB 3.0 Promoter Group announced this week at CES that some tweaks have been made to the USB 3.0 protocol that will allow it to be even faster. Currently, USB 3.0 ports are capable of transfer speeds up to a theoretical 5 Gbps.
The new specification will allow the ports to transfer data at twice that speed promising up to 10 Gbps of data throughput. The promoter group expects the supplement to the USB 3.0 specification to be completed by the middle of the year, which should mean devices supporting the higher-speed will be available then as well.
The higher rate USB 3.0 ports will be compatible with existing cables and connectors. The new specification will provide improved data encoding for more efficient data transfer and will offer improved I/O power efficiency. The faster specification will be compatible with existing USB 3.0 software stacks and device class protocols. The new protocol will also be backwards compatible with USB 2.0 ports and products.
The USB 3.0 Promoter Group says that the faster USB 3.0 port is targeted for industry review during Q1 of this year. More information regarding the specifications in planned for release will be available later.

So why not call this USB 4.0 or 3.1?

Seems rather confusing. Are we perhaps supposed to tell the difference based on a different shade of blue?

These are the same people who brought you USB Hi Speed vs USB Full Speed for USB 1.1 vs 2.0 (I still don't know which is which). BTW Shane did you a favor and left out that they're calling this USB Super Speed. I guess the next one will be Super-duper speed?
The industry would be better off if the marketer(s) thinking up these useless names were taken out and shot. Just call them 12 Mbps, 480 Mbps, 4 Gbps, and now 10 Gbps.

I'd be OK with just "USB 3.1", myself.
