I'm quite optimistic about Ziggler's future given the recent improvements to him and his booking over the past couple of months:
-They responded to his positive reactions from the crowd by turning him face
-They didn't butcher his character by making drastic changes to his persona or anything. He's still "The Show-Off", which has led to people on other forums to wonder why he's being cheered when he's acting like a douche. But that was his character before and it's his character now.
-He's actually winning matches instead of jobbing to virtually every person on the roster. His loss to Big E Langston on Raw doesn't count as a pointless job since it builds to the Summerslam match.
-He's actually gotten mic time compared to before. I expect more of this in the near future.
He isn't plastered all over Smackdown but he's not in the WHC feud so I don't expect him to be. He's in a mid card feud so he's getting mid card air time. Hopefully when it's over, he can re-enter the WHC picture. I personally like that they're breaking him apart from Big E and AJ before letting him win the WHC again, it makes for a more interesting angle where when Ziggler finally wins the big one again, it only occurs after so many trials and tribulations - winning the title but then nearly having to forfeit it because of an concussion, Del Rio nearly ending his career by zoning in on his injury, his girlfriend costing him the belt twice and then outright betraying him by instructing his former body guard Langston attack him, etc. It makes his win more of a feel good moment IMO.
