1. Sting Returns
Regardless of who ends up emerging victorious between Brock Lesnar and The Undertaker, some sort of twist at the end of the night involving Sting seems likely, and needs to happen. After all, we know he's in town that weekend because WWE's "vigilante" will be doing a meet and greet on Friday. It could be that he returns and costs The Undertaker the match as he's closing in on the victory or interferes and causes it to end in a no contest (which would actually be a perfect way to open the door to a third match between Lesnar and the Deadman somewhere down the line to decide once and for all who the better man is). Either way, Sting targeting The Undertaker would ensure that this year's SummerSlam lives up to the hype. Based on rumours that Sting was at one point going to be part of the Dean Ambrose and Roman Reigns versus Bray Wyatt and Luke Harper match, it's certainly possible that he could get involved with that, setting up a feud with Wyatt which could take place throughout the Autumn and Winter. Ultimately, it seems far more likely that he'll become involved with the main event, setting up that long rumoured match with The Undertaker at next year's WrestleMania. Whatever the case may be, prepare to hear the sound of crows as Sting makes his presence felt in some way in Brooklyn.
