    USB4 Specification is being finalised, will only use Type-C connectors.

    Being based on Thunderbolt 3 technology and offering up to 40 Gbps bandwidth, USB4 promises to be more than that. In fact, so much more that the USB Promoter Group is considering a new logotype and branding scheme. The current one is already complex enough, so expect some kind of simplification on that front. Meanwhile, USB4 will be backwards compatible with existing USB Type-C devices.

    I love how they claim up to 40 Gbps, like they did with 5 Gbps for USB3 spec & even back in the day USB2 at up to 480Mbps.
    Typical hyped up tech marketing to sell stuff, in reality, end users get no where near any of these speeds.
    Shops, online & bricks n' mortar are sill selling USB 2.0 sticks...

    careful, someone will make a smarmy "nobody could ever need more than 640K" comment.

    I like the physical connector, but I agree the bandwidth will see little use, even if it actually work in real life.

    It looks like the cable can be inserted either way, this should solve all the limitations of USB3.

    USB-C already does this.

    Am I missing something, or is this *absolutely nothing more* than a rebranding of thunderbolt 3, now that intel has made it royalty free

    Sounds like it's slightly more than that.
    Sounds like it's both USB and Thunderbolt protocols on the one "network" as it were with some smarter muxing (timeslots?)

    Like IPv4 and IPv6 coexisting.

    But yeah, kind of a snooze.
    Wake me up when they jam a multimode fibre into the same connector.

    USB & Thunderbolt already co-existed, as Thunderbolt uses the alternate-protocol lanes. I agree with Quadbox- this looks like usb 4 is just thunderbolt 3 rebrand.

    Which is fine, hopefully they keep the other requirements intel had on thunderbolt 3 ports (MUST support DisplayPort alt mode, MUST support usb-pd power delivery) to avoid the stupid muddle you can get now where some usb-c ports support one thing but not the other.
