Hmmmm someone is a crankypants. I'm not saying they'll never get an intamin, I'm just saying it's rather unlikely.
When a product requires you to purchase a bunch of unplanned crap to get it going, you generally will buy something else next time around. All of SFMM's B&M coasters have not been a problem at all, hence they have numerous B&M products.
All of the GIB's purchased by Six Flags required extensive and expensive modifications and gave the parks bad PR. Notice how nobody has bought anymore new GIB's since the three Deja Vu's and the Stunt Fall fiasco.
I'm just saying that unless there has been a huge shift in the park's management I'd bet people remember stuff like how difficult it was to deal with Superman and won't be interested in another Intamin product.
And I'm sorry if you're all puffy over the ride being screwed up before opening, but Tower Of Terror in Australia opened months before Superman, which means Superman wasn't the first of its kind. SFMM likes to advertise firsts (I've seen Batman as the first inverted coaster on TV when SFGAm's was), but this is another case of them being full of it.
It's like expecting someone who bought a Ford Pinto to buy a Ford Taurus when they could instead get numerous other cars.
