The Greatest Of All Time, John Cena, is now just five dates and less than three months away from his retirement. Naturally, the event marking his retirement will be one of the biggest events of the year.Over time, we have heard several rumors regarding the night Cena will retire, as well as some official announcements from WWE itself, which have gradually provided fans with more clarity over time.For instance, it had been speculated for months that he would retire at a Saturday Night's Main Event in December, or a similar TV special with Cena in some form being the titular name. The event itself is indeed billed as "Saturday Night's Main Event: John Cena's Final Match."

While Boston was rumored to be the working plan, WWE never officially announced it, and eventually went with D.C. due to the site fee they were paid.Domestically, the show will be broadcast live exclusively on Peacock, not on NBC, and will be the first Saturday Night's Main Event to be broadcast in this manner. Therefore, it will be a PLE of sorts, rather than a TV Special, although internationally, the show will be live on YouTube.Although the actual venue hasn't been officially announced yet, with tickets set to go on sale on October 17, one can expect an announcement by then. We do know that prices for standard seats range from $250 to $3,000, while the TV Ringside package (Row 1) costs $11,500.Who will be John Cena's final opponent?Ah, the question of the hour! There are several candidates for the same, and fans, of course, have several names in mind with regard to who will or should get the coveted opportunity to be John Cena's final opponent.It could be Gunther, or Dominik Mysterio, Bron Breakker, Drew McIntyre, or Brock Lesnar again... the list is endless, and everyone has their own theories and justifications as to why their guy must be the one who retires John Cena. So, let's have it out in the comment section!
