MadBananaRush has been around a while, and has good credibility, so I'm leaning towards believing it. And not just because I want to!
Question though, why would the race take teams to both Jamaica and Puerto Rico at this last stage? There must be direct flights to Miami from both those places. Somehow, it seems that one of those spoilers isn't right.
I also wonder if this isn't going to be a race around the world, but a race around half the world? Unless they go from London to Asia then back to North America...
Guess we'll know soon...
