I know Travis visited a WWE Smackdown/ECW show in Atlanta after leaving TNA and spoke with John Laurinaitis then, and I understood he had visited other shows since. Travis had hoped for a regular spot in Japan, and was thinking of getting into MMA but neither happened.
TNA had initially left the door open to use him again and did once but creative had soured on using him for future dates due to issues when he was under contract.
No info on when he might start.
Obviously this will fuel speculation he will join Christian Cage again in WWE.
