If anyone is interested, the video that I shot on Saturday when I was there showing some of the rumored areas of construction is posted.

Lots of variations on what else may or may not be changed, and I have some strong suspicions that some of those that people are confident of aren't going to pan out, and things that some think will change, won't, while others that may not be in the rumor mill now will change.
One thing I learned when I was there is that SDC is constantly refining, tinkering, and going over their plans. There were several versions of Fireman's Landing's layout. The area around Time Traveler was not the first plan (or the second, or the third...) And while they may be talking about doing something now, that could easily change in a couple of weeks when they rethink it a bit more.
