I've heard from some people that they are doing some initial work on it, and the hope is that it will be a relatively quick turnaround.
One potential wrinkle to the VPx and AVx codecs is that they know in advance when essential patents are going to expire, so tools could be designed in advance and only deployed when IP is cleared up. So there could be stuff that was too early for AV1 that could be reused. That's just my own personal speculation, though. But that could speed some things up.
People looking at AV2 have also been a lot more optimistic about it than AV1, which didn't get enough attention to HW decoder design optimization, or getting tools to work together orthogonally. One comment I heard is that one tool might be sharpening a pixel while another is smoothing it.
2020 should be an interesting year in the codec space, with AV2, VVC, and EVC all potentially being far enough along to evaluate, and H.264, HEVC, and AV1 still competing for current deployments. After UHD, HDR, HFR, and object-based audio all launching in 2014-2016, it's been a little dull around new media technologies. So I'm pretty amped by all the exciting fun 2020-2022 is going to be for codecs! It'll be an interesting mix of technical, business, and legal factors, and I really don't have a guess yet about what the codec world will look like in five years*!
And audio stuff is heating up with xHE-AAC, AC-4 with Atmos, and MPEG-H all going mainstream.
* Well, I bet we'll still be using MP4 as a container format.
