#2. New tag-team champions
Ricochet and Aleister Black have been on fire since their debuts on both RAW and SmackDown earlier this year. They've been one of the hottest tag-teams on the main roster and have already had a shot at the RAW Tag-Team Championships.
Although unsuccessful on that occasion, Black and Ricochet will have another shot at the gold on the RAW before WrestleMania as they challenge the RAW Tag-Team Champions - The Revival.
There is actually a decent chance that the RAW Tag-Team titles will not be defended at WrestleMania and The Revival vocal about wanting to leave the WWE could be a factor in that apart from the fact the card is massive already.
With that being said, it wouldn't be surprising if WWE decides to give Ricochet and Aleister Black a big win before WrestleMania. They are already booked for TakeOver in the night before WrestleMania although they could still get added to the Mania card.
