Thunderbolt's makin' like greased lighting. Intel has just introduced the newest revision of the interface, and it will be capable of 20Gbps in both directions (as opposed to the previous 10).
That's fast enough to transfer and play 4K video simultaneously. And it's all backwards compatible with old ports and cables to boot.
Intel just made the announcement at NAB 2013, but it will be a little while until the speed hits end-users; production isn't scheduled to kick into high gear until 2014. Of course, all that delicious throughput is limited to devices that support it, but it will be a lovely burst if you've got devices that can use it. [Engadget]
