I think that there are 11 legs, the mega leg only being counted as one leg. I don't think that the amount of legs/locations speculated adds up since we know that we only have one Kazakhstan leg. The only thing I can think of that it will make it 12 legs is two legs in either: India, Cambodia, or Philippines. I don't think the Philippines as two legs. India could be two legs but having the amount of three legs in one city I don't think would happen. The only thing that is similar to this S14 China legs were their were two legs however the second leg being a double length leg making it have the amount of three legs, but the first China leg was in a city in southern China and the second leg (double length) being in Beijing. So, unless Cambodia is two legs, which i don't think, this makes us have 11 legs.
