#3 Jimmy Uso could appear on WWE SmackDown
As mentioned on the first slide, WWE tries to keep current couples together on the same brand. Bianca Belair and Montez Ford are both on SmackDown, and before she revealed she was pregnant, Becky Lynch was on RAW with Seth Rollins.
For one other reason, however, that trend of pairing married/dating couples might end with Jimmy Uso's return to WWE. The entire storyline painted around Universal Champion Roman Reigns has been about family, the Head of the Table, and acknowledging those facts. Jey Uso went through the trials first and was even saved at one point by Jimmy. Jimmy "acknowledged" Reigns so that Roman would stop attacking Jey.

While it has been nice to see Jey branch out into singles action in WWE, the tag team division needs him much more. The Tribal Chief storyline will continue as long as Reigns is Universal Champ and it will likely involve other family members. Since Jimmy already had a brief moment in the storyline, he'll be thrust back into it once he returns from injury.
Jey even hinted that his brother would be back within the next month or so. There's also a strong possibility that the heel Usos dethrone the Street Profits for the SmackDown Tag Team titles.
