#3 No chance of a Shield reunion (for the time being)
One of the possibilities that would have kept Roman Reigns on RAW is a potential Shield reunion. Had Dean Ambrose decided to stick around, I'm quite certain that Reigns would have been a red brand member, for a showdown between The Shield and The New Day down the line.
But, Dean Ambrose is gone and to the best of my knowledge, will not be back for at least 6 months. And this rules out the possibility for a Shield reunion, allowing WWE to actually try out other possibilities.

Of course, Dean Ambrose may be playing us all and it may just be a ruse to create interest in his departure. But whatever the case may be, I doubt that he'll be a part of the proceedings during the Superstar Shake-Up.
And this makes me think that Rollins and Reigns will be in two different brands.
