Yes, he's said that. Just from comments Colt has made, the sticking point has always been that WWE wants to own the Colt Cabana name and Colt wisely does not want to give that up. WWE really needs to get over that, and maybe they have.
Colt Cabana is such a better name than Scotty Goldman it's not even funny.
They don't own the copyrights to names like CM Punk and they've done just fine with him. Colt can easily be a mainstay if they give him the ball to roll with, the only reason he had such a short run last time is because they stuck him as enchancement talent.
