From Mike Allen's Playbook:

C-SPAN's Steve Scully tells us that Helen Thomas, who has been missed in the White House briefing room lo these many months, will be returning soon (probably tomorrow's briefing) to give Dana Perino a workout on her way out the door, and to welcome Robert Gibbs to the NFL. Tour-guide trivia: Each seat in the briefing room has a nameplate designating an organization: CBS, New York Times, etc. Helen Thomas's seat -- literally front and center -- is the only one with a person's name on it.
