Man, what a cool addition! It is indeed the world's first racing launch coaster, "coaster" being singular. It definitely looks to be a Premier-built ride, because those trains are unmistakably Sky Rocket trains with some nice dressing. I agree with the idea that both WCR and Maxx Force are designed by Ride Centerline, because the flow and elements are very similar to each other. I would say the same for Steel Curtain, and I might even guess Alan Schilke could have done them all as well! I wonder if the renders just recycle the track style or it really will have something similar
