Six Flags Fiesta Texas - Batman The Ride, S&S Free-Spin 4D
Six Flags Magic Mountain - Twisted Colossus, RMC Mobius Hybrid Makeover of Colossus
Six Flags New England - Wicked Cyclone, RMC Hybrid Makeover of Cyclone
Six Flags Mexico - 242 ft. Star Flyer
Six Flags Over Texas/Six Flags St. Louis - Battle For Metropolis, Sally Corp. 3D Justice League Dark Ride
Six Flags Great Adventure/Six Flags Discovery Kingdom/Six Flags Over Georgia/Six Flags America - Looping Dragon/Bourbon Street Fireball/Dare Devil Chaos/Joker's Chaos, all are Larson Giant Loops
I think this excerpt from the LA Times article linked at the top sums up the Looping Dragon additions-
In perhaps the most disappointing announcement of the 2015 season, four Six Flags parks are to install pendulum-style thrill rides typically associated with traveling carnivals and county fairs. Adding insult to injury, Six Flags is intentionally misrepresenting these rides as roller coasters.
An absurd addition that I hope backfires on Six Flags so it doesn't happen again.
Apart from that, I think the pair of RMC Hybrid Makeovers were expected, they look great (also expected). It's evident that Six Flags names their coasters by drawing xtreme(!) sounding adjectives from a hat, possibly to save money, unless they reuse a franchise name (Batman The Ride, Goliath, X-Flight...). The names on the Larson Loops are about as creative as the decision to add them to anything other than a county fair; Dare Devil Chaos (wtf?), Looping Dragon, Joker's Chaos. Bourbon Street Fireball is the one out of the bunch with a name that won't make you cringe when you hear it. Idiots came up with the other three.
One other thought, with the S&S Free-Spin going to Fiesta Texas, I wonder if Six Flags is done with Intamin? Off the top of my head, prior to Green Lantern, El Toro was the last Intamin installation.
