The New York Times reported (in a story about Olbermann’s new show and former time at the MSNBC) that the network is now developing a show for Hayes, a Nation contributor and frequent guest host for Rachel Maddow and Lawrence O’Donnell:

Guest bookings are also important because popular guests can become full-time hosts. Mr. Hayes, for instance, is a frequent substitute for Lawrence O’Donnell and for Rachel Maddow, two MSNBC anchors. Now MSNBC is developing a show for Mr. Hayes. Mr. Uygur was groomed the same way.
“There’s a whole new batch of young people we’ve brought in, because we want to keep feeding our system,” Mr. Griffin said, naming as one example Alex Wagner, a writer for The Huffington Post.
