John Cena was named as the "cover Superstar" for WWE 2K15 from 2K. According to this handy press release, "Cena's image reflects his commitment, strength and leadership both in and out of the WWE ring." His face will grace the cover of the game when it releases October 28 on the PlayStation 4, PlayStation 3, Xbox One, and Xbox 360 platforms.
"It is truly an honor and privilege to serve as the WWE 2K15 cover Superstar," said Cena. "2K has a tremendous history of sports simulation games and cover athletes, including Michael Jordan, Kevin Durant, LeBron James and of course, Dwayne 'The Rock' Johnson. I look forward to carrying the flag for WWE 2K15 and introducing the incredible next-generation of WWE gaming to the WWE Universe."

Cena has established himself as one of the most prolific WWE Superstars of all time. A pop-culture fixture, Cena is frequently recognized for his film, television and music endeavors, as well as for granting more than 400 wishes to children with life-threatening illnesses through the Make-a-Wish Foundation, more than any other celebrity. In addition, Cena is one of the world’s most popular athletes across social media with more than six million Twitter followers, as well as 27 million likes on Facebook, making him the most-followed active U.S. athlete on Facebook.

I know Cena does a ton of work with the Make-a-Wish Foundation outside of the ring. I believe at last check he's fulfilled over 400 Make-a-Wish requests, and this was back in February. In fact, I have heard far more about that then anything he's actually done inside the ring. He seems like a great choice for the cover just for that reason alone.
