This is a 'scorecard' by conference for 2021, the 22-nd for the 64-team playoff system where every conference gets an automatic bid. [There was no tournament in 2020 due to COVID-19.] You can find the full results elsewhere.
My original motivation for this summary was the thought that the regionals are a major source of inter-conference and inter-region play that helps one evaluate the relative strength and (possibly) future selection or seedings of teams from various regions and conferences. I think it still serves that purpose.
Current status:
Super regionals are in their third day.
Super regionals are complete! On to the CWS.
Vanderbilt and Stanford were the first teams into the CWS,
while Mississippi State and Virginia were the last ones in.
National 15th seed Florida went 0-2 for the SEC on their home field.
Here is the 'histogram' of the success rate for the 2021 NCAA regionals.
I tally a Regional champion under "win" and the Super-Regional champion (the team that goes to the CWS) under "champ" so the "champ" column is unchanged from the previous 48-team system.
Notes:
There are no changes in the conference lineup BUT the Ivy League did
not play baseball this year due to the COVID-19 pandemic..
As a result, there will be only 30 conferences with an automatic bid,
so 34 of the 64 teams are selected at large instead of 33.
The * below indicates that the conference was
guaranteed a slot in the CWS because both teams in a particular Super Regional
were from the same conference.
In this year's case, in Regions 3 and 14, this resulted from a 3rd seeded team
from the SEC upsetting the national 14th seeded team from the Pac-12.

Effect of format update made in 2018:
Although it has no effect on the organization of the table shown here,
there was a significant change in the playoff format that marks a final
break with a long-standing tradition in tournament seeding that will
affect these stats.
The NCAA seeded teams from 1 to 16,
and paired up the regionals so that 1 plays 16, 2 plays 15, ..., and 8 plays 9 in
the respective Super Regionals.
This now mirrors what has been done in Basketball "forever".
Although not publicized, this led to a significant change
in who a conference team might face in a Super Regional.
Until 2018, it was forbidden to seed two teams from the same conference so they
would be "expected" to meet in the same Super Regional, but that is no longer the case.
There are multiple instances in 2021 where the top seeds in a Super Regional pair
are from the same conference.
?? update as needed ??
There are two regional pairs with SEC teams at the top,
plus one each for the Pac-12, ACC, and Big 12 conferences.
