I'm curious why some of you are arguing that removing the remainder of the Lost Continent would make Islands too much like "Harry Potter's Islands of Adventure" ...wasn't Dueling Dragons a part of the Lost Continent? If anything the LC is the oddball in the park, as it has no brand name compared to the rest of the park. Marvel, Dr.Seuss, Jurrasic Pack, and to lesser extent Toon Lagoon, all have huge branding behind them. Lost Continent seems to be a minor area of the park, and Im pretty sure it's the least popular besides that Mythos place. I havent seen the Sinbad show or the Posidon show since the park opened, and im sure a lot of people feel the same way. Making the remainder of Lost Continent, an expansion of Harry Potter a MUCH bigger brand seems like a no-brainer.
Now as far as what will happen and when it will happen, personally I think the only reason they would fast track an expansion is because they want to remove Lost Continent completely from the map as soon as possible. That being said, considering the amount of time and detail that went into the WW, they would really need to get this on the fast track to meet the 2013 rumored deadline, and keep the same quality. I just dont see them tearing everything down and starting fresh..as it would be too costly and time consuming. Im thinking a much more minor resurfacing of the existing buildings instead, and maybe a new structure for Posiden if they choose to do a new ride.
