I predict an INTAMIN Hyper to SFOG next year themed to Superman. Most likely a SROS cookie cutter. But for other parks:
BGT-B&M Hyper
CP-B&M Flying Coaster
Valley Fair or Worlds of Fun-B&M Inverted
IOA-Vekoma Flying Dutchman
SFWoA-Intamin Hyper
BGW-Drachen Fire
SFEG-ANYTHING! I feel bad for them.
SFMM-B&M Flying Coaster(to compete with CP)
PGA-TA2K
PKI-WOB (Wife of Beast)
Holiday World-Something Steel
SFOT-Titan Jr. The Giant among kids coasters, oh wait, that's Goliath Jr.
SFAW-Vekoma Flying Dutchman
That's all for right now, I have to think too hard to come up with rumors I've read. Hope you enjoy.
