AMD's Zen 3 CPUs (Ryzen 4000 series) are expected in the second half of 2020, built on a 7nm+ process. They will likely maintain AM4 compatibility.
It recently came to light that AMD is already deep into developing its Zen 5 architecture, slated to succeed Zen 4 after 2022. Notably, the team that just wrapped up Zen 3's development is leading the charge on Zen 5. AMD's CTO Mark Papermaster revealed this in his speech.
This marks the first official confirmation of Zen 5 as a distinct branch in the Zen architecture's evolution.

Ryzen 4000 series processors are set to launch in the second half of 2020. Based on current information, they'll use a 7nm+ manufacturing process.
Currently, Zen 3 chips are listed as compatible with existing motherboards. If you already own a Ryzen 3000-based system, you'll likely be able to drop in a Ryzen 4000 processor. However, full confirmation isn't available yet.

Platform launch | 2017 | 2018 | 2019 | 2020 | 2022 |
Looking further ahead, Zen 4 isn't expected until 2022. Before that, 2021 should bring a Zen 3 update dubbed Zen 3+.
⤢ ВІДКРИТИOn top of all this, Zen 4 remains an extremely nebulous architecture. It's 99.9% likely that its processors will switch sockets and probably move to DDR5.
Based on this, it's reasonable to assume Zen 5 will be an update for the upcoming platform, much like Zen 1 and Zen 2 were for AM4.
