Interesting.
It's also worth mentioning all the news and drama coming out of Disneyland this week regarding Star Wars Land. In summary; On January 10th the Rivers of America (which has 4 different rides operating on it in Anaheim, one ride less than what DHS has operating right now) will close, the Disneyland Railroad will close, and Fantasmic! will go dark. These closures will last between 15 and 18 months, until the summer of 2017.
Disneyland's River and Railroad will both be majorly re-routed and re-Imagineered. The Fantasyland Theater will close by spring as the new railroad tracks go right through that space. Star Wars Land will heavily remake and enlarge the entire northwest quadrant of Disneyland, adding 14 acres to the size of the park when it's done in 2019.
Beach that canoe, and shut down that locomotive - Darth Vader needs that land!
If they are going through all that trouble for Disneyland, they certainly are going to do the same scope at DHS. I can't believe they would try to do chintzy stuff like salvage Echo Lake, instead of just bulldoze the whole area and start from scratch for DHS.
