Who's Coming Back To KARK Mornings

Anybody have the scoop WHO is coming back to KARK mornings? KARK is currently running promos about the mystery?

Update: Maybe I should have checked my tip box. A tipster says, "Melissa Simas to replace Barbara Roberts as morning show anchor at KARK-4."

Additional: Another tipster sent in this: "Barbara Roberts told KARK morning show viewers that today was her last morning show because of a "high-risk" pregnancy. She'll know be doing the noon show and health segments."
