I hope the rumor for the four loops and under Arrows isn't true. Those are what made all of those parks great. Carolina Cyclone was the kick-ass coaster at Carowinds for 12 years until Vortex came along in 1992. Save the Arrows!
If you think about it KI is next in line for a new coaster. That is if you go off of 2008-2010. CW got Behemoth in 08, KI got Diamondback in 09, Carowinds got Timmy in 10. So it could only mean KI gets a new coaster in 13, considering Leviathan came to CW in 12.
