WWE World Heavyweight Championship Picture
Currently the World Title picture is going pretty well as you have a ruthless beast wanting to destroy the champion before he got suspended just because he didn't get his rematch. Their is Roman Reigns who may not be super popular but can still deliver solid performances in the ring and Randy Orton who has a valid case for a match since three hours before Rollins cashed in at WrestleMania 31 he defeated him. The current champion is going to be on TV every week which is a change from what normally happens (last eight months) when the champion would appear every two weeks for about a month, then take three months off.
The current matches I'd expect would be a Triple Threat Match at Extreme Rules between Rollins, Reigns and Orton then at Payback I would have Randy Orton face Seth Rollins for the title in a No Holds Barred, Steel Cage or any other kind of stipulation. Before ultimately running into The Beast Brock Lesnar at SummerSlam 2015 in a No Holds Barred Match where Rollins would (with a lot of help) pick up the victory over Lesnar before losing the Championship to Roman Reigns sometime down the line.
Intercontinental Championship Picture
The Intercontinental Championship just like the US and WWE World Heavyweight Championships all seem to be slowly regaining the prestige, Daniel Bryan is now a Grand Slam Champion in WWE thanks to his IC Title victory, at WrestleMania 31 after that victory backstage he got congratulated by Bret Hart, Pat Patterson, Roddy Piper, Ricky Steamboat and other about being a very deserving IC Champion.
The contenders for the Championship include the man that Bryan threw off the ladder to get the Championship Dolph Ziggler, the man who returned on the March 30th RAW by turning heel and Brogue Kicking Daniel Bryan, Sheamus. Then there is the former Intercontinental Champion Bad News Barrett who lost the title at WrestleMania 31 in a 7 Man Ladder Match to Bryan.
They should have Daniel Bryan vs. Bad News Barrett for the title on either RAW Next Week or Smackdown Next Week, then they should do Daniel Bryan vs. Sheamus at Extreme Rules then Payback. From there he would have defeated the man who gave him the 18 second loss at WrestleMania 28. Bryan could then go into a feud with maybe Bray Wyatt or Dolph Ziggler that may see the other guy win the title before losing it to Bryan again within a month. That would lead into SummerSlam 2015 where there would be a Unification Match between United States Champion John Cena and Intercontinental Champion Daniel Bryan.
United States Championship Picture
This title picture may be looking a bit thin in terms of the amount of people involved but the three who currently feel involved are pretty important feeling (except Dean Ambrose). In this championship predicament you could have John Cena and Rusev have one final match at Extreme Rules in a Flag Match where (not the Flag Match from SummerSlam 2014 where you had to defeat your opponent in a match then pose with your flag, but the other one where you grab the flag). You could have Cena and Rusev both grab their flags at about the same time before declaring that Cena won.
In the future you could have Ryback, Luke Harper and Dean Ambrose all involved in the United States Championship picture before they do the Unification Match at SummerSlam 2015 between Cena and Bryan.
