I think that all but the Power6 would, yes. First of all, the Power6 Conferences make enough money to sustain this so eventually, if they go this route, they could find themselves as the only ones at the table. That means all of the TV Revenue, all of the money associated, which could then support the long term ramifications of what I believe this will mean.
All others, I think the get out of the business and focus on their real revenue opportunities, which are education and R&D. This way, they avoid the long term cost/problems that are sure to come from this.
What does that mean? Lots of athletes that no longer have an opportunity to get educations via athletic scholarships.
