It depends. Usually in a case like this, one side will be very motivated to be done (especially when the list of who is going to get put under oath comes out, most Cos would not want their CEO put under oath and asked questions). In this case IMO it's just a matter of how big a check PC is gonna write. So until that point it's all about them trying to get leverage. I don't see this dragging on for years given the contracts involved.
