Source: The Wrestling Observer Newsletter -- While John Cena and WWE are both publicly claiming that they expect Cena back by WrestleMania 30, the real expectation is that he will be able to make it back in time for the Royal Rumble, which is just under five months. That is believed to be pushing his recovery time slightly, something Cena has a habit of doing when coming back from injury.
Oh, without a doubt he'll appear at the rumble. That'll be his comeback date for sure, unless a huge match is booked at the TLC PPV in preparation for WM. (Like a WM implication match) Whether he is ready to work or not at the rumble, he'll appear and take a few bumps, but he won't win. At least I hope he doesn't....
