Simple, do not reuse the existing ride system.My concern is if they brought the ride back, how do they counter the security issues the brought the ride to it's slow death to begin with? Back in the KBT days and early KOD days, the cars were evenly spaced out as a continuous load, as you may expect.
But due to people leaving their cars during the ride (and allegations of people having sex on the ride), they tethered the cars 5 together, with a very large gap between. You would sit in random sections of the ride for an eternity as another section loaded. Not to mention having a Knott's employee riding in the back. Not to mention the unbelievable lines and waits this process created.
Until that issue is settled, I can't imagine it returning.
