#2. Who will challenge the champions not chosen by the Royal Rumble winners?
Three of WWE's four world championships were defended at the Royal Rumble. Universal Champion Roman Reigns barely retained his title, winning by disqualifying himself. He went on to cost Brock Lesnar the WWE Championship and revealed that he was in cahoots with Paul Heyman all along.
It looks likely that The Beast will be out for revenge, leaving the field wide open for RAW stars to step up and challenge WWE Champion, Bobby Lashley.
Similarly, both current women's champions were involved in Ronda Rousey's last match from her first WWE run: a Triple Threat Match at Wrestlemania 35. Therefore, either can be challenged by the former UFC Champion, leaving the other needing an opponent for the biggest event of the year.
These questions are likely to be answered at the Elimination Chamber on February 19.
1. Who will the Royal Rumble winners challenge at WrestleMania 38?
Brock Lesnar and Ronda Rousey won the men's and women's Royal Rumble matches, respectively. The former UFC stars have reason to challenge either champion, making their WrestleMania choices a very intriguing notion.
WWE could inject swerves and surprises such as putting Seth Rollins in the Universal title match as a repeat of WrestleMania 31 main event.
