Could The Rock win the WWE Championship

The Royal Rumble is upon us once again. This PPV could set the tone for 2013. Imagine if you will. The Rock winning the WWE Championship....then what?!?! Is he going to come back...? Take the belt with him to all the movie premieres he has in this year!?!?! That would give WWE more publicity. I guess all that is possible, but I don't think it will happen. Of course stranger things have happened in the WWE. Anyone remember RAW's New Year's Eve episode or Christmas eve episode? I think I've made my point.
