The Wrestling Observer is reporting WWE and 2K chose John Cena for this year's WWE 2K15 cover to increase numbers. Cena is more well known than Daniel Bryan, and was actually picked to be the cover athlete several months ago, before Bryan even won the title at Wrestlemania XXX.
Cena has never had a singular cover, and the belief is that Cena haters are still going to buy the game regardless.
BP: Cena hasn't been featured on a cover since Smackdown vs RAW 2011, which also featured Big Show and The Miz. There has been discussion online about when, not if, Cena would get a cover since he is the biggest star they have, and he hasn't been featured the past several years. With the 'Special Edition" of the game, and fan and contest cover art, the 'haters' may not even keep the Cena cover art.
WWE Hiring Former TNA Knockout
Former TNA Knockout Rosita has been used as one of Adam Rose's Rosebuds on WWE TV lately, and WWE may be close to signing her. Rosita, real name Thea Trinidad, was prominently shown on screen during Money In The Bank and RAW, which may be a sign they will sign her soon.
