Speculation
Leg 1: Tokyo (Art/JJ)
Leg 2: Luang Prabang (Bonehams)
Leg 3: HCMC (NEL)
Leg 4: Dubai (Eliza/Corinne)
Leg 5: Uganda (KOR)
Leg 6: Uganda (One of Reillys, Afghanimals, and Jan/Brit)
Leg 7: ? (elimination, 7 -> 6)
Leg 8: ? (elimination, 6 -> 5)
Leg 9: ? (NEL)
Leg 10: ? (elimination, 5 -> 4)
Leg 11: ? (elimination, 4 -> 3)
Leg 12: USA (final 3)
So my guess is we are on Leg 7 right now, but considering theres only +/- 1 week left until the scheduled finish, it is possible that they already used all NEL/KOR legs (either LP or HCMC had two legs) and we are on Leg 8 now.
