Maybe I shouldn't presume, but if I go on their past track record with the brand split, they're not going to split up a married or in this case engaged couple. So I'll stick with that prediction.
And when it comes to who gets who, I think SD will got a lot of big names from Brock, Roman, Becky, Seth, and then fill out their roster with other smaller names from there. I still think Raw will keep a decent amount of big guns, including Bray.
If you take away Brock, Roman, Becky and Seth, there are basically no big guns left, lol.
Bray is not a big gun. Not yet. He's the biggest star in the business for this specific moment in time, but in a weeks time, he's gonna be a nobody again, and Vince will never trust him as one of his top guys. He can be a big gun if he beats Seth clean. Maybe Raw gets Charlotte, maybe, I doubt it. If they do, she's pushed, but she has no fans. She feels like a B level star, always has, just pushed as an A level star. There's nobody else, AJ Styles is not a big star, he's always been a midcard main eventer. Daniel Bryan is ice cold and will never get back the momentum he fluked into in 2013, etc. Braun's a jobber with no credibility. Owens isn't a big gun and SmackDown is probably keeping him anyway.
Raw is gonna be a B show, that's all there is to it. Even if they keep Seth, which I expect they will, because I just don't see Bray winning the title. I virtually NEVER get what I want and I REALLY want this. Badly. I cannot see it happening. The evidence is so overwhelmingly, mindblowingly in favor of Seth retaining. As much as any feud I've ever seen.
