Yea but i don't believe that "spoiler" review. The guy who has apparently seen the film still thinks Beak is Beak, he isn't called Beak anymore, they changed it to Bolt. If he had seen the film you'd think he would know the name of the character right?
I reckon Weapon XI will have his arms cut off, and from getting crushed in that tower/reactor collapse or something like that, his healing factor will overload and cause his body to reject the other augmentations. Leaving a failed, reject Deadpool right at the very end. What Reynolds has said matches up with what that Spaced and Confused guy said, that Weapon XI is the experiment, Deadpool is the failed experiment, the thing that remains after it goes wrong.
