Whether the next WWE World Heavyweight Champion is crowned at the Royal Rumble, Fastlane in February, WrestleMania 32 in Dallas, or perhaps not until several months after that, many people have been speculating exactly who will be the man to wear the title after Roman Reigns. Some fans had predicted John Cena to tie Ric Flair's record of 16 World championships during the first half of this year, but that went out the window once Cena went down with a shoulder injury that required surgery. Other fans thought Roman Reigns wouldn't even hold the WWE Championship until WrestleMania 32, but as has been made very clear over the last several weeks, plans can always change and they did in The Big Dog's case. WWE have been forced to be flexible with their plans as of late with many injuries eliminating their top main event superstars on the road to WrestleMania. The WWE World Heavyweight Championship is usually central to WWE's plans and, unlike in years past, the next WWE Champion is anything but obvious. This article takes a look at the 10 most likely superstars to be crowned the WWE World Heavyweight Champion once Roman's reign comes to an end.
