Maybe Vince waits for the heel turn until the opportunity presents itself. Which means that there has to be a real successor. Someone that can carry the company as top face just as good as Cena can. Like in 96, Sting was there to take over Hogans spot and in 2001, Rock was there to take over Austins spot.
Actually, he wasn't.
The night after the heel turn, he fucked off for about four months to film a movie and didn't even acknowledge Austin when he came back. (actually, WM17 was more or less the end of the rocks full time wrestling career when you think about it) That's part of the reason the turn didn't really take off, after the Rock had gone, there were no strong babyfaces left for Austin to bounce off. HHH could've filled that spot nicely, but as we know, that's not how it went down.
At the moment, only Punk can really be the ying to Cena's yang, and there isn't anything stopping a double turn at or around wrestlemania season. Besides, Cena turning heel allows WWE to wean fans of of Cena in the long run.
