USB4: spec ready, adoption expected to start from 2021. Thunderbolt 3 will become part of USB 4 standard.
PCIe 5.0: introduced in 2019, mass production in 2020
PCIe 6.0: planned to be introduced in 2021

The current generation is Wifi 5, or IEEE 802.11ac

The next generation is Wifi 6, or IEEE 802.11ax. You would need BOTH Wifi 6 routers AND Wifi 6 devices to take full advantages of it.

Wifi 6 is faster than Wifi 5, but may not be that obvious.
The true difference is that Wifi 6 can support more devices
- MU-MIMO, or "multi-user, multiple input, multiple output", is upgraded from 4 devices to 8 devices
- OFDMA, or "Orthogonal Frequency Division Multiple Access", allows one transmission to deliver data to multiple devices at once.
Improve battery life, especially for low-power, IoT devices.
Better security: WPA3

Wifi 6 adoption is going up. Now high end devices, like iPhone 11+ and iPad Pro, are supporting Wifi 6.

Some motherboards have Wifi chips built-in, otherwise you can buy a PCIe Wifi card or USB Wifi Adaptor
