Kurt Angle mentioned to the UK Sun that he would like to return to WWE at some point. 

“I can’t say when”, Angle told the UK Sun. “My (TNA) contract is up in September and I’ve left my options open. I’m very happy in TNA. Dixie Carter has treated me very well and always been there for me. But, I can’t lie to myself anymore. I can’t lie to TNA or WWE. Yeah, there is that desire to go back. I just don’t know when. It could be this year. It could be next year. I don’t know when.”

Kurt Angle also mentioned in the interview that at some point he would like to have a feud with CM Punk or Daniel Bryan. You can watch the full interview in it’s entirely at this link.
