Prediction
With Libby found guilty, and the news that Cheney has suffered a blood clot, I predict we see Cheney resigning due to health reasons at some point. This keeps Cheney out of court, allows Bush to install another toady in his place, and in the eyes of this administration, stops the bleeding caused by outing a CIA agent from reaching the president.
Not that aren’t other issues to go after him on, of course.
