As for the question, I don't see any reason why he can't atleast level his star power if WWE market him and invest a hell of alot into him now that he's a face, he's starting to be advertised alot more when WWE are promoting stuff like tours, games (he's the main star on the cover of SD v. Raw 2011 over here in the UK and Cena isn't even on the cover), if he is shoved down are throats and utilized correctly, calling him Cena's equal could be a legit claim in 2 years time IMO. Plus he has youth on his side and Cena I don't think is going to be the biggest star all the way untill he calls it quits, unless WWE invest in him nonstop for another 5 years. This is coming from a big Cena fan btw.
