I just got home from IOA, and I'm gonna go against the grain and say I think we got another week, at least, until actual softs start, maybe/probably longer. Until I see the gates open and close while they test vehicles... Until I hear sound coming from the RV speakers... Until I see any type of movement from the AA "drivers", I'm guessing (hoping) they won't let guests on.
I want to ride when it's ready. Not when a screen or two, or a vital sound cue, doesn't fire. Now, that said, I will of course be first in line when softs start, for better or worse.
But the walls are still up. There's landscaping crew all over the site digging and adding things, and I haven't seen a vehicle test yet where the temple gates open and close. (Unless I missed one on YT, which is possible.) The gates are my indicator. When I see that working, I'm going to assume we're getting closer.
Having said all that, I will say... they were playing new Skull Island music by the Mess Tent and I almost teared up it was so beautiful.
