Saw this on Screamscape. It apparently seems that the new coaster could possibly have restraint belts that go over the shoulders. Not sure why that's needed though, unless there's a brand new type of restraint system being used. Also, you can see the word "Tempesto" in the background, so if this concept art is legitimate, I'm locking Tempesto as my guess for the name.
2015 - New Roller Coaster / TEMPESTO or DIAVOLO - Under Construction - (2/20/15) A piece of leaked concept art for the new, and still unannounced, Tempesto coaster at Busch Gardens Williamsburg was posted to the ParkFans forum the other day. I don't know if this is a final or near-final piece of artwork, but the train style is interesting as the normally flat fronted Premier Rides train is shown with a decorative nose-cone. Even more interesting is the fact that they have added a pair of restraint belts going from the lap bar up and over each rider's shoulders. This makes me wonder if we will see a modified restraint system put to use here instead of using the standard lap bar only system.
