Very nice photos of all the progress at HKDL!
I'm actually very excited for Grizzly Gulch. I don't know how the queue or ride effects will compare, but the track layout and general organization of the coaster there look more interesting to me than Expedition Everest. It really seems like the Imagineers took all the concepts they've used in various coasters before (launch, backward segment, etc.) and synthesized them in a way that builds and improves on past efforts.
Although the Grizzly Gulch work does seem pretty far along, I wonder whether they'll really be done in two months, which that casting call seems to suggest is the planned opening date for the land.
And Mystic Point really looks like it'll be quite expansive. Even though it'll only be one land, I get the feeling that it won't seem too condensed. The Adventurers Club building seems pretty substantial as well and, as people have pointed out, there's room behind both Mystic Point and Grizzly Gulch to further expand these lands with additional attractions in the future.
I can't wait to see the final product! I'll definitely plan to visit HKDL next year if I can.
