The upcoming WWE World Heavyweight Championship match between John Cena and Brock Lesnar is being billed as their final battle.

"With Cena chasing his elusive 16th world championship reign, part of the intrigue of the Royal Rumble pay-per-view is whether Cena will be successful in his final attempt to capture a world title for now," states Bleacher Report.

But is the outcome already decided?

Rumours suggest that Lesnar won't be hanging around at WWE for too long. Reportedly, he is planning his exit in the coming months - as a result John Cena is expected to be the sureshot winner of the eagerly awaited match.

According to IBT India, Lesnar's contract will expire in early 2015 soon after WrestleMania 31 and the WWE execs may then want Cena to be in the limelight.

Apparently the network is said to have instructed the merchandise department to stop manufacturing materials for Lesnar.

Other rumours circulating the web also state that while Cena will defeat Lesnar in the Royal Rumble match, the duo will face each other again in WrestleMania 31.

It remains to be seen how things unfold following the World Heavyweight Championship match in 2015.
