In terms of advancing his character, they absolutely should turn him. His character gets heat that only X-Pac could understand.
But they are a business first now, so they won't. He pushes too much merchandise and fulfills an ungodly amount of make-a-wish requests.
They'll tease it every year around this time in hopes of getting the people that hate him on his side. It doesn't work and he'll be back to his ol' trick the following Raw. Maybe if they didn't **** up so much at development.....
Oh and Punk is definitely losing. They wouldn't burn takers streak on someone who won't be on TV for awhile post mania.
