I expected in the 3rd quarter for possible release, however, it appears it will be a bit longer.
But actually I have viewed much info of autel Evo 2 like the post EVO II https://www.autelpilot.com/products/autel-evo-2-drone (at least in price and function) and it will be released in March 2020 but when will Mavic 3 available, at least there should have more info for us to reference.

no one knows

Last rumours I heard from bill the drone reviewer was it was delayed and the M2P was still selling so well.

No one knows, specially with the pandemic happening.

This release date was again pushed back to summer 2020

The sooner the better.

Looking forward to the release date.

I have reason to believe that it will come out in January 2021, due to the fact that the Mavic 2 pro is still popular. I will definitely buy the Mavic 3 the day it comes out, because right now I have the Mavic Air 2 and the Smart Controller, and I would like an even better drone for me. I also want to buy the Mavic 3 for it's accessories, because hopefully the DJI goggles will be able to connect to the Mavic 3.

Hi Eric.C  I think its pics and release date will be posted on the official website of DJI or in DJI FORUM
