#1 John Cena appears and is taken out by Bray Wyatt

One of the big things going on in RAW in recent months was the new Bray Wyatt's vignettes ahead of his return. Weeks of segments culminated in Wyatt's return last week after Finn Balor's match.
The lights went out and the masked 'Fiend' Bray Wyatt appeared in the middle of the ring and took out Finn Balor with the Sister Abigail. Wyatt's first match looks set to be against Balor at SummerSlam next month.
Moving onto RAW tonight, one legend who conspicously hasn't been confirmed to appear is John Cena. However, there is still some chance that he does make a surprise appearance. If he does, WWE could have Bray Wyatt, who does have a history with John Cena, appear out of nowhere and take out Cena during his segment.
