The Big Ten football media package is in final stages of negotiation as we all know.  This week's addition of USC and UCLA will certainly have an impact on the final deal.  The conference states that further expansion is not imminent. 

If media reports are correct that the conference is waiting on Notre Dame, how does that work if this package is announced next month as expected?

Do these deals have renegotiation clauses should additional members be added?  Does the Big10 go with a shorter contract length (unlike the long deal the ACC is currently trapped in) to preserve options?
