At this point Johnny is a veteran of wrestling having held World title gold in various companies at this point which is a drastic change from his days in WWE when he was considered an up and comer. Many think that Johnny could've been given the opportunity to carry the company as World Champion in WWE, but was never given the chance to shine. If John did return to the company he could still deliver on the level that he did during his first run with the company. Also he could not only help give a fresh face contender for the mid level titles, but at this point I believe that Johnny would also be able to gain a stable spot in the main event picture.
There is a good amount of conversation going on right now that John and his fiancé could be looking for a new home in the near future, but at this point there is no discussion about John returning. I would like to John return to WWE especially if the company also bring his fiancé with him as it would allow Morrison to have a different feel about him this time around.
