According to King Dave, there's been an idea pitched that would see Bray Wyatt turning on Matt Hardy in the near future. The idea is that Bray turns on Matt and that he takes over leadership of SAnitY when the faction hits the main roster. There's no word on if WWE is going to move forward with this, but the idea has been brought up. As for SAnitY, it also doesn't mention exactly when they're set to hit the main roster but the report states that the latest batch of NXT TV tapings could be the faction's last.
If this is legit, I'm not certain how I feel about it. Bray has been floundering since his brief run as WWE Champion ended at WrestleMania last year and his apparent face turn and subsequent teaming with Matt Hardy is something that looks to be welcomed as a breath of fresh air by a lot of fans. SAnitY, on the other hand, does seem like a group that'd fit in well with Bray as they're all about chaos, anarchy and destruction; also, there's a good possibility they won't be just the mostly silent followers that Harper and Rowan were.
Right now, Matt Hardy and Bray Wyatt seem poised to win the Raw Tag Team Championship and, as I alluded to, his partnership with Hardy feels like something fresh. I'm not a big fan of "Woken" or "Broken", whichever term you want to use, but a lot of others are and this could be something Wyatt needs. Leading SAnitY seems like a step back into his old role but that might not be such a bad thing if Vince allows SAnitY to be...well SAnitY.
