This season has been an interesting experiment for The Amazing Race.
On the plus side, the four-person Detours are cool, teams aren't losing because of random cab driving, and as usual, the scenery has been beautiful.
On the negative side, there has been an insane amount of bunching, the foreign country language/signage problems aren't coming into play, and I don't feel I've gotten to know all of the individual racers that well.
I think the Bransens will win, and what's more, I think they'll win on a big contribution from Dad Bransen. They've shown him saying, many times, that he's dragging his daughters down. It would be a great story arc to have him essentially hit the game winning home run.
I think the Weavers will come in second. They work well as an Us vs. Them team, but I don't think they're as smart or as athletic as the Bransens. Mom Weaver certainly doesn't foster a friendly, outgoing attitude in her family.
The Linz family, while the most likely to win a footrace, has made a couple of dumb mistakes along the way. Also, I don't really see much of a storyline for them, other than the sister proving herself to her brothers. A Linz win would be the least dramatic.
