When does Las Vegas return?

Las Vegas starred James Caan, Josh Duhamel, Nikki Cox, James Lesure, Vanessa Marcil, Molly Sims, Marsha Thomason, and eventually Tom Selleck. The series originally centered on Ed Deline, a strict ex-CIA officer who serves as the president of operations for the Montecito, a fictional hotel and casino on the Las Vegas Strip. Danny McCoy, a former Marine Counterintelligence/HUMINT officer, later becomes the resort's new president. Caan and Cox departed in 2007, after completing season four, and Caan wanted to resume his film career, and Cox was let go due to budget cuts.
