#4 Should Happen: Becky Lynch wins the Raw Women's Championship

Becky Lynch is indeed living up to her 'The Man' gimmick and not only are her promos in line with her new look, but her walk and her talk backstage are also in line with her new gimmick. She is the best thing there is in the women's division of the wrestling business right now, and it seems like she will keep moving up the ladder as Wrestlemania comes around.
With two months to go between Wrestlemania and Royal Rumble, there is a possibility that even Charlotte Flair will be added to the mix. It is a possibility that Becky will win the Rumble match and go on to Wrestlemania, but she must win at the grandest stage at all costs.

#4 Shouldn't happen: Asuka loses her match

Asuka had the undefeated streak until last year's Wrestlemania and then she lost to Charlotte Flair which was devastating for fans and her career in general. She was the most dominant force in the company and did regain her stature after winning the Smackdown Women's Championship during a triple threat match which also included Becky Lynch and Charlotte Flair.
After a character of this stature, it would be better off if she continues her streak and not lose the match at the grandest stage of them all for the second year in a row.
