There's been a bit of buzz on social media regarding this and someone realized something absolutely brilliant about that tease!
When Hurler first opened, of all the coasters that are currently in the park (so exclude the defunct Shockwave from this), the park had four inversions, all on Anaconda. Now, the park has since added Volcano, Flight of Fear, and Dominator. Volcano and Flight of Fear both have four inversions, Dominator has five. Now do the math and you get...
4 (Anaconda) + 4 (Flight of Fear) + 4 (Volcano: The Blast Coaster) + 5 (Dominator) =
17 Inversions At Kings Dominion
So when Hurler first opened, the park had four inversions. So assuming it's opening again in a different form, the park will have twenty inversions. That's three more than it has now, so assuming this refers to inversions in the park (which it very likely does, notice the upside down T in the tease), it suggests that RMC Hurler will contribute three inversions to the park's inversion count.
Also, completely off topic, but that tease really reminds me of this creepy video, with the dark technology vibe and pointed mask. Anyone else notice that?
