They can threaten all they want, but the B12 is unstable and will implode. It's a matter of when, not if. You know it, I know it, and they know it. The problem is, does another conference want a whiny, sue-happy bitch? They're just making themselves look bad, IMHO. Instead of threatening law suits, they should make themselves look better by at least appearing to want to work WITH other teams, not against them.
Just my 2C.
