It's possible. Who knows.
That isn't guaranteed though. But He shouldn't have left, I mean seriously how long was he over at the WWE and got nothing? Jeff Hardy came back and he was instantly thrown into the main event scene. I mean ya Christian win the ECW title but come on, its the ECW title.Considering that he just returned to tv and will probably be involved in a world title match at Mania, I doubt it.
And how is he being treated bad?
By treat him bad i will take that as your take on him being a main event star in TNA and as of so far in WWE he has been no more than a mid card wrestler bar his run in ECW but that isn't treating a wrestler bad because WWE is so much bigger than TNA so someone who has been a main event star in TNA most likely won't be a main event star in WWE or at least straight away. I really do believe that had Christian not been injured we would have seen Edge/Christian at WrestleMania 27 as i believed that Christian was going to turn heel before his injury but the injury and how long he was going to be out for played a HUGE part in where we are now.just wondering cause wwe treats him bad
