I'm sure we're talking about different topics, but it may just be that I am so tired--I can't quite get a solid idea of which project you two are alluding to (you can PM me if you'd like). I'm almost 99.89% sure we are not talking about the same thing...
As far as I've been told, aside from some technical difficulties with the KUKA system over in the Potter Box, everything else is moving along at a strong pace. I've heard nothing else negative yet.
Just so I don't end up sounding negative about this overall, I should put it out there that I have high hopes for the Wizarding World of Harry Potter and all of its attractions. I miss the Lost Continent already (and will miss its remains once Potter absorbs them down the line), but I'm all for change. My trust in Universal Creative was strengthened so much after The Simpsons Ride debuted, because for the first time in a while, I felt like the replacement/update of the attraction (one which I was a huge fan of) was handled extremely well--to the point where I almost prefer the new ride to the original. And on top of that, they gracefully threw in several tributes to the former attraction itself, so I have many reasons to be thankful.
Knowing how meticulous Universal Creative had to be over Potter, especially with Rowling hovering over them like she does her bank account, I can't imagine it being anything short of amazing.
Yes, Disney may have lost the ability to premier a KUKA tracked ride, but thats not to say that they've not got enough to counter in the long term.
Unless Universal is prepared to start offering new attractions annually (which I am all for), sooner or later they will revert to their short-spurt additions scheduling, allowing Disney to do what it does best and continue to bolster their already strong catalog of park attractions across the resort.
With Rip, Ride, Rockit and Potter taking up such a strong portion of the budget (and previous additions like the Simpsons and Disaster also on the bill), I can't imagine Universal will be able to keep at it. They may come out ahead this year or the next, but Disney will continue to bring new attractions at times when Universal simply can't... I'm optimistic for both parks about the way the upcoming years will play out--and I'm playing for both sides of the field!
