Great shots, Awhen. Thanks for posting!
Based on the slow pace of construction for this attraction, it's looking like a summer 2016 opening to me. There is NO rush on this project like they did with some of the other projects they've done. They've been moving dirt and pouring foundations for months now. Something else will come for 2015...likely something small or a series of small projects before rolling out the big guns (Kong) in 2016 again. However, that's my own speculation based on what I'm seeing/reading on here and several other sites. I have zero insider knowledge.
As for the Kong running rumor, yeah, I'm with Disneyhead on that one and I'll believe it when I see it. There are ways to fake having Kong "run," but an actual RUNNING animatronic? No way. At least, not one that *RELIABLY* runs 12 hours a day, 7 days a week, 365 days per year.
