I might be wrong (ask the wife), but I think the Supreme Court ruling will be the end of the NCAA as we know it. College sports will continue in some new form with the control of revenue vs non-revenue changing. Some random thoughts:
Football championship super conference with 60 to 100 members where the entire season is a playoff. Maybe same though larger for hoops.
If revenue athletes are paid, there may be more balance to "amateur" sports where the school foots the cost. Could impact Title IX counts, maybe?
