I will be surprised if we ever again see any kind of major sanctions from the NCAA. The Penn State lawsuit pretty much showed they have very little power. They are basically relegated to determining player eligibility (until some school sues them over that) and making rulebooks for the various sports.
For now, it's time for the accrediting agencies to step in. Schools that are playing games with fake classes and are bending academic standards need to lose their accreditation.
In the long term, perhaps the federal government needs to set up an agency with subpoena and legal prosecutorial power to oversee college athletics.
