I recall seeing a video of them testing the coaster. I think this may be because the coaster takes too damn long to get the ride up the lift hill, and that's with an EMPTY coaster. They might be adjusting it or adding more to it so it doesn't suck as much.
I remember visiting Universal Studios early spring (and RRR was still missing some pieces) but there was a section there where you could exit the park another way- I could cross through the construction, see the big drop above me, and I ended up near the Blue Man Group building. I wonder if that'll still be open like that when it opens - be a great picture place.
Each of these delays and "coming soon" is kinda making the hype die for me. and like Eric says, I feel like the delays are a bad sign.
All I know is that, in general, the longer you make someone wait for something, the better that person expects it to be. Good if you can meet that standard; bad if you can't.
