No one is really predicting that Dean Ambrose will walk out of Roadblock with the WWE World Heavyweight Championship, but the fact that the title is on the line three weeks before WrestleMania has to show that WWE is at least entertaining the possibility of changing things up, right? Its entirely possible (and even likely) that this event will just maintain the status quo: Brock Lesnar will interfere in the main event and cost Ambrose the title, allowing he and Dean to have their Mania match with just a little more fuel on the fire, and Triple H will walk into Mania to face Roman Reigns as planned. Or Could Ambrose (and possible Lesnar) be injected into the main event title match somehow, making it a multi-man match that adds just a hint more intrigue than the Roman gets revenge storyline? It would be a major shakeup to the Mania main event, but weve seen the last two world title matches at WrestleMania get a major wrinkle shortly before the event (Daniel Bryan at XXX and Seth Rollins at XXXI).Betting lines have Ambrose winning at 4/1 and Triple H at 1/5, so you can see that the odds are against it happening. But you just never know
