We know nothing about one ui 4 just yet, theres no beta or anything atm, just keep an eye on there YouTube channel or socials to keep upto date

Pixel phones are still in the beta process now(beta 4),I believe two more betas are still to be released before a stable android 12.
So will be waiting a little while longer before other phone brands get to try it out.

September/October the beta program will probably open up to the S21 series.
