I thought the big rumor is that they are, in fact, finally getting a lot of flat rides soon. What basis/info do you have to say that it won't have any?
With a tentative name of "Adrenaline Alley", that definitely implies more than one attraction is coming. To me, the question is, is a flat ride package coming as it's own announcement, or will it be in addition to a new coaster? Are these two separate events, or one big one? And if separate, what's coming first?
And yeah, SFMM and reliability is pretty funny. But, even I feel SF doesn't intentionally want to get something that's already known to have problems. They're more than capable of creating problems all on their own without any per-existing conditions.
