#4 Having Finn Balor come out as 'The Demon King' to defeat Bray Wyatt
Let's be clear about something right at the start. Bray Wyatt is the most intriguing thing about WWE at the moment, and there is no way that he should eat a pin at SummerSlam. There is no doubt in my mind that he should go over Finn Balor.
Which is why Balor should show up as plain old Finn Balor and not The Demon King when the two men square off at SummerSlam this time. Not only will this mean that either The Fiend or the Demon King has to lose the match, it will also signal the end of the feud. It is confirmed that Balor will take a leave of absence after SummerSlam, and this may be a great way to prolong the feud.
Balor could return around Survivor Series for revenge against The Fiend. This could result in a WrestleMania 36 match between The Demon King and The Fiend.
