It's being said that at the moment the three people the powers that be are most high on are Roman Reigns, Bray Wyatt and Bad News Barrett. The report also states that when Reigns wins the world title it's likely to be at a major PPV and made into a 'moment'.
The plans discussed for him were either for Reigns to work with Brock Lesnar or The Rock. Apparently The Rock has asked to work with Reigns at some point before he retires and as they're cousins the feud pretty much writes itself though it would mean Rock having to win the title again. Rock also technically still has a rematch clause after his loss to Cena at WM29 so this wouldn't be too implausible either.
