Latest news on Screamscape is that it Intamin was the initial company to do the project, but now it is said B&M beat them out.
Knott's Berry Farm(8/16/12) While Intamin was heavily rumored for the next Knott’s coaster project, the latest buzz I’ve been hearing does seem to indicate that Intamin may have been dropped entirely from the project in favor of B&M.
(8/15/12) Knott’s new 2013 coaster looks like it should be moving full steam ahead at last. The rumors all point to a Giga sized coaster, possibly in the range of 325-340 feet tall. Intamin is still the rumored designer, though I have heard B&M’s name dropped as well a couple of times. All those wild survey markers seen around the park about 18 months ago may all come into play once again, with a crazy ride layout that could very well run wild over a large portion of the park.
My personal thoughts are that this is looking like 2014 or late 2013 (year round park). But I was wrong with this before. I remember Kings Dominion rumors kicked off later than normal (though the land clearing was evident) and out of almost nowhere, they announce I305. And with not much being noted for 2013 other than GateKeeper and SoB destruction, maybe CF has the funds for it and already have it planned out.
