If john cena turns heel will it be the beginning of a new era like the attitude era?

i think at mitb john cena will retain the wwe title with the help of vince beacuse he doesnt want cm punk to walk away with the title and his top star be fired. the hometown in chicago will riot thus turning cena heel and the next day cena does his own shoot promo like cm punk to the fans for booing and disrespecting him all these years.
