I don't see edge turning face just yet, it is just a slight tweak in his character now he been seperated by vicky.
Here's hoping for an "amazing feud with punk" - its fresh, not been done before (they never did follow up punk's MITB cash in last year...although edge was on smackdown, punk raw....) and as mentioned in other threads, punk definately needs some credibility and some mic time, what better way then to feud with one of the best on the mic and one of the top/if not THE top heels in the wwe, and i think they will put on great matches (have had really good ones in the past in one off occasions)
On a side note, do you think they will split edge and vicky officially? or just leave them as married on seperate brands?
