I disagree with this being the safest option for two reasons. First, Cena is really starting to show his age as he becomes more injury prone. I think that the recent pushing of new stars like Bray, Reigns, and Bryan is a sign that the WWE is more interested in pushing new talent than in keeping the old. After all, the more time they spend on making Cena a star is less time they have to build up new stars for when his career ends. I think that the focus on Roman Reigns on last night's Raw is a sign that the WWE is looking into who the new top stars are going to be, and while Cena will still undoubtedly play a huge role in the future, I think its too soon to give a belt.
Also, it must be acknowledged that there are a lot of hardcore WWE fans who dislike Cena but own the WWE Network. Does the WWE really want to put losing those fans up as a risk but putting the most polarizing superstar back in the championship role? I don't think so, or at least, I don't want to think so. Cena just hasn't been having a great year, as I feel that Bray completely outshined him in their feud.
Besides, keep in mind that this is a title that was taken from the most over man in the company, Daniel Bryan. Whoever wins that title is most likely going to get a lot of heat whenever he returns. In my opinion, it would make a lot more sense to build up a new heel. As such, my choice is also Bray Wyatt, and I really like larisano's plan to do it. I personally would set it up so that Reigns has cleared the ring like he has in battle royals and the Royal Rumble, only for Luke Harper and Erik Rowan to hit the ring after having won the tag titles. They attack reigns, but get speared and superman punched respectively for their efforts, only for Bay to hit a Sister Abigail with Reigns onto a ladder. Bray goes up to retrieve the belts.
In my opinion, none of the wrestlers who have been in the title picture for a while need the belts, but Bray is clearly ready to be in the main event picture after his work with Cena. With the titles, Bray wreaks havoc on Raw, terrorizing both the Authority (setting up a face turn) while feuding with the likes of Reigns (who he did not beat cleanly) and possibly Orton if the Authority sends him in to deal with the situation.
