Countdown to Armageddon
They just turned punk instead of cena... obviously they can't turn him now as long as punk is heel but they could've on the 1000th episode or anytime before that
Eh, I still wouldn't call Punk a full-blown heel, mainly because the guys he's going against are still more boo'd/hated in most places than Punk has been since his "heel" turn so really, what does that tell you?
He hasn't started running down the "Universe" or done anything morally indefensible so the window is still technically there for the double-turn. What's really preventing it is the same PG era garbage that has made everything lame and shytty for the last several years. According to PG rules, heels must be cowardly and weak and faces must be smiling goons with no personality. Cena's still the best man for that job.
