Haven't delved deeply in the numbers but I'd say thus far it appears the SEC has underperformed while the ACC and Pac 10 has exceeded expectations in the Regional/Super rounds.
SEC sent 9 teams to tourney 7 NS and 4 top 8. 2 in CWS with 1 possible
ACC sent 7 teams to tourney 1 NS and 0 top 8. 1 in CWS and 2 more possible
Pac 10 sent 6 teams to tourney 2 NS and 1 top 8. 2 in CWS
I suppose a lot will depend on what happens today and then certainly in Omaha.
