I don't know what's been mentioned in this thread already so I apologize if I reiterate anything someone else has already said.
In regards to X-Pac coming back, he will probably be in a backstage capacity, not in-ring, which is sad, because although I am not a fan of X-Pac the person (aka the crap he did to Chyna,) I AM a fan of X-Pac the wrestler. With that being said, even though the original DX was HHH, HBK, and Chyna, it would still be nostalgic and, in my opinion, cool if DX was reformed once again with HHH, HBK (in a non-wrestling capacity) and X-Pac. HHH is being advertised for the MitB PPV so who knows. It probably won't happen, but one can wish, can't one?
In the same nostalgic wish, it would also be cool if HHH, HBK (again, in a non-wrestling capacity) Kevin Nash and X-Pac formed the Kilq (not just backstage.)
There are a lot of wrestlers who have done some quite bad things in real life. Stone Cold allegedly abused Debra, Jeff abuses drugs, the whole Benoit incident, X-Pac doing what he did to Chyna, but I have to say that doesn't take away from what they have done and can do in the ring. Minus Jeff Hardy maybe, because his real life spilled over into his professional life, but I am still a Jeff Hardy fan and hope he really is clean and can stay clean.
That's all I have to say about that.
