The WWE Royal Rumble 2015 card will be live on pay per view and the WWE Network this Sunday night. It is one of the biggest wrestling shows in any calendar year, and always sells strongly on the question of who will win the Rumble match and go on to headline WrestleMania. It isn't just the 30 man Royal Rumble match that will make the 2015 show feel special. There is also a very interesting WWE Title match as the co main event, with major superstar and WWE Champion Brock Lesnar making a rare in-ring outing. The challengers will be top draw John Cena and elite worker Seth Rollins, so it promises to be one of the best triple threat matches in recent years. There's genuine mystery over who will leave as WWE Champion. The rest of the card is a little bland, but the hour rumble and at least twenty minute triple threat will make up for that. The undercard matches include The New Age Outlaws vs The Ascension, Paige and Natalya vs The Bella Twins, The Usos vs The Miz and Damien Mizdow. The preshow will be The New Day vs Tyson Kidd, Cesaro and Adam Rose. Despite the cobbled together undercard, this still looks to be one of the most fascinating shows of the last twelve months. Who will walk out WWE Champion and who will they be facing at WrestleMania 31? All will be revealed!
