CBS confirmed today that David Letterman will be retiring in 2015. No successor has been announced yet, but expect feverish speculation and pie in the sky suggestions. Louis CK and Conan O'Brien seem to be Twitter's top two choices, though the network could choose to move Craig Ferguson into the coveted spot.
