#5. Lars Sullivan to finally debut
Once upon a time, it was rumored that 'The Freak' Lars Sullivan was going to take on John Cena at this year's WrestleMania and then Sullivan's main roster debut got pushed back, and pushed back and then it simply didn't happen with the Superstar allegedly taking time off after suffering a panic attack.
Now that WrestleMania is finally here there's a small amount of buzz being drummed up again that WWE are going to pull the trigger on NXT's big man and have him make his presence felt on 'The Grandest Stage of Them All'.
Whether Sullivan finds himself wrestling in an impromptu match against John Cena or someone else, or if he just runs in and attacks someone, an appearance from him would be a genuine surprise for the WWE Universe.
