4. Sting returns
There were plans for Sting to return at Battleground to help Roman Reigns against Bray Wyatt, but that plan was dropped.
After Battleground, reports came out that Sting would return for a match at SummerSlam 2015. He was supposed to be involved in 6 man tag team match, where he would team up with Dean Ambrose & Roman Reigns to face the team of Bray Wyatt, Luke Harper & a mystery partner (as Eric Rowan is injured).
However, WWE has already made Roman Reigns & Dean Ambrose vs. Bray Wyatt & Luke Harper official for SummerSlam 2015. This means that Sting might not be returning for SummerSlam after all.
But there could be an angle where WWE books Sting to return directly at SummerSlam 2015, and that too in the main event. If WWE doesn’t want any of the 2 stars to lose clean, then they can book Sting to distract Taker, and helping Lesnar win the match. This would help in setting up their epic clash at WrestleMania 32.
