In my opinion, I feel that this season's kind of like TAR 13 in the sense.
Meghan and Cheyne are getting the Nick and Starr edit, very likeable at the beginning, then their nasty and scheming sides show later but if you noticed, they weren't portrayed in too villainous a way, such that while they lose some fans, they still remain largely likeable to many.
Brian and Ericka are getting the Ken and Tina edit, lots of bickerings through the race, but they were nice to other teams. Remember Tina always giving directions and helping other teams? They got a good edit towards the end but they still finished second, which I predict will be Brian and Ericka's ultimate placing. What's more, they haven't won a leg, and it hardly occus that teams who haven't won a leg will win eventually, besides Eric and Danielle.
Sam and Dan are perhaps getting the Andrew and Dan annoying edit, BUT the former's a million times better than the latter.
That's my take, I think Meghan and Cheyne win eventually. Which will be boring because for one, they've won SO MANY legs and for another, I don't really like them now and I really want Brian and Ericka to win. But well, my favourite team winning doesn't happen to me often, in fact it hardly happens, so I'll just prepare for a Meghan and Cheyne win and not get my hopes up. =(
