Based on the way the video promo was recorded, it sounds like Cena is going to give the last match to some new talent that nobody really knows.
Probably safest. Cena is obviously going to win the match, and it’s not going to be part of any ongoing “storyline,” so you might as well give it to some kid who will put on a good show, not be hurt by taking the loss, and then can use it to propel his career forward.
Of the names released so far, none of them fit that bill, and it definitely won’t be any of the names released so far.
Once all 16 names are announced, I’d put my money on whoever is the youngest.
