The Pi 3 (and previous models) had an issue of bottlenecked bandwidth when using Ethernet and USB simultaneously. Is this resolved in the Pi 4?

Yes, it resolves it.
“While Raspberry Pi 3 Model B+ added Gigabit Ethernet connectivity, throughput on Raspberry Pi 4 is free from the single shared USB 2.0 channel to the SoC.” (https://www.raspberrypi.org/magpi/raspberry-pi-4-specs-benchmarks/)
7To be more specific, the USB host controller is connected directly to the SoC via a PCIe bus. The Ethernet Controller is built directly in to the SoC. Jun 25, 2019 at 10:04
3rejoice! Though I suppose it would be nice if there was a PCIe built into the board for utilization.– tuskiomiJun 26, 2019 at 13:59
