For a cool $17 million, I don't think HFEC was completely satisfied with the ultimate reaction to MM, and I have serious doubts now that one will ever surface at SDC unless considerable changes are made to the concept. While MM's thematics and details are awe-inspiring and really boosted DW's aurora and quality appeal, the ride itself must fall far short of HFEC quality for opinions to be so mixed about it. For $17 million they could have gotten a lot more with a different ride system. It's a shame though, cause the concept looked so good on paper.
Of course, Gerstlauer has recently over-hauled the design of the Euro-fighter to be smoother, but I don't see the new design fitting SDC very well.
I'm glad DW is going to B&M for their new coaster, I think it bodes well for us in the future. I'm hoping the chain learns to stick with quality ride makers like B&M for their big coaster projects, and saves the huge theming budgets for other types rides that could really use it.
