Is the Pac 12 Network holding back?

Since it's launch the Pac 12 Network has not announced ONE cable or satellite carrier who has agreed to carry the Network except for the original four of Comcast, Time Warner Cable, Cox Communications, and Bright House Networks. I find it hard to believe that they don't have at least one or two cable companies "under their belt." They must have at least a some cable company in "Podunk wherever" signed up. At least, let's hope so! They are playing this very close to the vest.  Let's hope they are not like the Wizard of Oz.
