I realize everyone says USH is cheap. I agree that they were cheap. They are spending quite of bit of cash to transform this park into a viable vacation destination. King Kong 360, Transformers, Despicable Me, the new central park, Shrek queue. Plus according to the people you have been talking to an attraction every year till Potter. Even if its a small little somthing. They are investing some serious cash. Not DCA cash or even USO, but for USH, I believe they are doing what should have been done years and years ago.
In my opinion, they're still cheap. We haven't truly seen an attraction from Universal that matches the scale of WaterWorld, Jurassic Park or Back to the Future. Transformers was a step in the right direction - don't get me wrong - but we still haven't seen anything earth shattering. Jurassic Park was earth shattering, and so were WaterWorld and Back to the Future. All three were major innovations in the theme park industry. Not to discredit Transformers, but it's using the same underlying technology as Spiderman - and that was introduced in 1999.
Until Universal makes another monumental leap (like what they did with Potter), I'll still remain skeptical with Comcast's involvement with the park. Until then, management appears to run on the same motive as they have in the past decade or so: spend enough to get the crowds in, but don't go beyond that.
...and the rumors that you've pointed must be taken as that - rumors. While we're confident about the "attraction every year" notion, we've clearly noted that the word "attraction" encompasses many meanings to Universal, and shouldn't be taken as gospel for anything major. Central Park and everything else are pure hearsay, and we have no confirmation on either two.
Long story short: the potential's there. We just haven't seen it realized yet.
Also keep in mind that King Kong and Transformers were all done under General Electric and under the park's old regime. There hasn't been a change in park-level management for many years, and for all we know, things won't change with the parks unless the current management can clearly demonstrate that they're committed. That, or a drastic change in management structure could and should occur.
As it stands, Despicable Me does not appear to be the step in the right direction. From what we hear, expect another Back to the Future rehash. That - to me - doesn't inspire confidence.
