Well this particular rumor seems plausible because it would cheap to convert LMA to Cars, but I thought they were getting rid of LMA because the show itself was an expensive show to perform multiple time a day. And no offence to the insiders but someone was posting photos of animatronic mermaids for POTC a while back, but at the last minute they were cut from the budget, my point is nobody really knows anything until it's finished and in the meantime anything is possible. I think it's more likely that some of this info gets leaked on purpose to see how fans react to it on-line, and then use that to help make a final decision, like the first verion of New Fantsayland that was deemed "too girly"
