Realtek is almost ready to launch a more affordable all-in-one USB dock for laptops. The latest prototype features a 10 Gb/s USB-C 3.1 Gen 2 main port splits the bandwidth across a great selection of connectors. Even though there is no Thudnerbolt 3 support, all the connector chips are proprietary, so the dock should feature a sub-US$100 price.
