The literal next G CPUs are 4000G and should be released this year. But the next gen after that 'Cezanne'- 5000 series laptop/ G processors- will be Zen3, and the desktop Zen3s are AM4 so their APUs should be too. They are currently slated for 2021 release.
Shifting to AM5 probably depends most of all on whether DDR5 RAM is actually ready for mass production- and I'm not 100% sure they've even stopped fiddling with the official specs for it yet. I'm sure AMD would like to offer AM5/ 5000 series/ DDR5/ PCIe 5 (maybe) for marketing purposes, but if there isn't enough DDR5 available we may get one more gen on AM4 after 4000- or even a dual socket compatible release as AMD has done before with AM3/+. They might postpone a release for DDR5 to get ready as well, but probably don't really want releases to be dependent on 3rd parties more than they are.
