There's some interesting information regarding DCA's Wonderful World of Color, Grizzly River Run Upgrade, & other attractions from Screamscape.com
2009 - Wonderful World of Color - Rumor - (3/16/07) Screamscape sources tell us that the current budget for the Wonderful World of Color nighttime spectacular was set at $50 and we’ve heard that the show will feature some new style projection concepts never seen before. One interesting rumor going around is that California Screamin may be covered with LEDs to turn it into a bright color changing background surface for the show. There has also been some research done into next generation water screen technology but no promises into that making it’s way into the show for sure due to various reasons and concerns. For example the show can be seen around the lagoon… and you can really only project images onto water screens in one direction, so it would have a weird affect for those viewing on the wrong side. You could use a ton of them around the lagoon’s viewing area, but then the close proximity can create problems where you add a little wind and end up soaking your audience, as fans of Fantasmic can certainly understand.
2009/2010 - Grizzly River Run Upgrade / Grizzly Peak Railroad - Rumor - (3/16/07) I’ve got a couple of updates to the various improvements in the pipe for Grizzly Peak. According to sources, the addition of animal animatronic figures to the mountain will indeed happen. The true question is only a matter of “when” the budget and timeline approval for this “placemaking” project will be greenlit. The funny thing is that (according to our source) attendance at DCA is finally (and unexpectedly) on the rise which is causing some concern in the upper management about what kind of negative guest impact so much construction all around the park from the many placemaking projects will have. The goal was to have all of the various placemaking items finished in time for the 2011 10th Aniversary of DCA, but they may be tempted to push a few of them back. As for the rumored Grizzly Peak Railroad… it’s been confirmed as a blue sky project right now but it’s been gaining some credibility lately. With the goal to rejuvenate and improve DCA all around, we’ve got projects already in the pipe for Paradise Pier (Midway Mania & Wonderful World of Color), Carland looking like it may take over the Farm area, and long term plans to replace Aladdin in the Hyperion Theater with a new musical as well as possibly import Philharmagic all within Hollywood Blvd. This kind of leaves the Grizzly Mountain / Condor Flats area of the left out in the cold, so Grizzly Peak Railroad may be the perfect fix. While anything can change at this point, the current plan is for a slow family friendly mine train experience (compared to an outdoor version of Knott’s Calico Mine Train) and not a new coaster thrill ride.
