UPDATE: Later in the call, they again noted that Tough Enough is returning as "original programming" on the Network. No filming or debut dates were announced.
ORIGINAL: During today's WWE's First Quarter Investors Conference Call, they were discussing ways that they will be adding content to the WWE Network. When they were listing new events (Monday Night Wars, a new season of Countdown) they listed "WWE Tough Enough". We'll have more on the story as it develops, but it sounds as if the show will be making a return via the WWE Network.
