^^Assuming the Mack rumor has any validity, perhaps a comparison to Lost Gravity is more in order:

My hunch is still that they are going to try out the spinning cars for the big marketing angle, but if that falls through and the ride is fairly unpopular after a couple seasons they could easily switch out for the wide cars. I absolutely do not expect them to do both at once.
mhguy77, even though it's a "big" coaster, it's not necessarily going to be super long. They rarely make long coasters these days. More cost efficient to focus on the big elements and let it hit the brakes hard leaving the audience wanting more. Who knows though, with block sections and potential launches or holding drops it could last a couple minutes. There are certainly a lot of footers, so who knows how much track they plan on shoving in there.
