    USB 4 specification are out. Backwards compatible with USB 3.2, USB 2.0, and Thunderbolt 3 cables. Yep you read that right. One of the big updates is the integration of the Thunderbolt 3 standard.

    USB4 allows for two-lane operation on existing Type-C cables and up to 40 Gbps operation on certified 40 Gbps cables. So expect them over priced cables sold to people that don't need it but it's faster innit. Though if you need it, that's twice as fast as the fastest USB 3 drives.

    USB-C connector will the default cable interface which seems a robust connection to me. I reckon you could run your OS over one of these quite nicely, though will be interested to see if it's sorted the USB bus bottlenecks you seem to get sometimes.

    I believe you can do data and video over the cables, at the same time. So this really could become your one size fits all solution. Wouldn't it be good to only have to keep one type of cable around... Looks at my pile of current USB assorted cables....

    They have only just ratified the specifications and I don't think there is much out yet. I'd imagine it's not going to cost much more than usb 3 in hardware but probably a premium on over speced cables and beefy power supplies. You can already get usb C chargers with 60w or so and they don't seem that much more expensive. So I think it will not affect prices too much and just be a gradual upgrade for all usb 2/3 connectors.
