ASU made a huge move to expand into California and they are worried that leaving the PAC would kill applications there, so they are not all in on the BIG12. Their president also said they are making their decision completely independent of Arizona and that AZ going does not affect their decision. Who knows how truthful his words are, but they are making a big California push which would be hampered by leaving.I believe that the only possible concern Arizona may have would be their state board of regents telling them that they cannot accept an offer and leave ASU behind unless ASU chooses to be left behind (which may well be what tomorrow's regents meeting is about).
