I think there will be some stations that will still not play their stuff (I truly hope a majority of them do). The mainstream press will jump on this story, painting them as a victim...."Poor little Dixie Chicks....". But their sales should come NOWHERE near the multi-platinum successes of "Fly", "Wide Open Spaces", and "Home".
Of course, CMT (long de-programmed from my DishNetwork) will likely play their video every hour and do a month-long special on it.
