From St Louis paper this morning:

Post-Dispatch columnist Bryan Burwell reported Sunday that a Big East source told him that if the league got its operations in order quickly, it could add two more teams for next season and SLU was a leading candidate.
Along with SLU, Dayton and Richmond are considered candidates to join the league. The league would probably take just one Midwest school to keep a regional balance, though the possibility remains of expanding beyond 12 teams.
If SLU and one of the others go, Datyon would be a real geographical outlier for the A10 unless they added schools in the midwest. Maybe Dayton would go to the MVC to replace Creighton.

It would seem that 12 is still possible for next year, and that Richmond/VCU would be in the mix to balance the geography.
Other articles noted the confernce had applications from a number of schools.
It might be a SLU/Dayton and Richmond/VCU cage war at this point.
