I've look at that race promo at the end of episode 1 and dissected it. From it, I predict the next two teams eliminated (in no particular order) are Elliot and Andrew and Joey and Danny.
Why? well Joey and Danny don't show up it in at all, every scene I checked, they are nowhere to be seen. I'll admit that's a little disappointed, cause it's funny. I thought I would dislike this team a lot but they've got this incredibly weird charm. Maybe it's their bumbling nature or how they seem different from their "Jersey Shore" appearance. I'm willing to give them a chance.
Back to the promo, every other team is featured and at first I thought Eliott and Andrew weren't in it, I was wrong, they were in it only for one very (emphasize very) short section near the end showing them pushing the cab that's apperentely in Paraguay. If that is indeed from Paraguay, then it safe to assume they don't make it far after that. I'm not disappointed at all, they seem like nice guys, but seriously, has there ever been any other team that has been given less screen-time?
Just my thoughts
Next two teams gone:
Elliot and Andrew
Joey and Danny
