Maybe. It's anyone's guess really which team (if any) will be dominant when the new regulations come in. Mercedes would certainly appear to be the most likely to come out ahead though. As for Red Bull, a lot of their high performance this season was relative - because Mercedes were hit so hard with the changes affecting low-rake cars differently to high-rake, which is not a thing that can quickly be designed out. And another part of Red Bull's performance this year was due to the flexible wing that got banned by the time of the French GP I think. A lot of people notice Mercedes did much better in the second half of the season, and think this was mainly due to a Merc upgrade... but a large part is surely due to the RB downgrade.
I really hope we see several different teams fighting it out next year. We don't want to go back to a situation where one team is by far the best.
New regulations have been told to the teams some time ago and they had all the time to prepare well for the 2022 season where supposedly we should see these new regulations come in.I too hope for a more open Championship where we can have more than 3 teams fighting for the title and not like this year where except Monza and Hungaroring all other races were dominated by Redbull and Mercedes.
