I wonder what the latency on this is... given that "The Simpsons" is an animated show with a long lead time, when's the last episode that will air with Harry Shearer's voice? The end of the 2015-2016 season?
See the notes at http://tvtropes.org/pmwiki/pmwiki.php/Main/AnimationLeadTime, there's a whole section on the Simpsons there. They use editing and rush animation to add in some topical items, but the majority of the content has to be voice-recorded months before the finished episodes are on TV.
