Concentric controls... neck-through... whether I like it or not I can certainly applaud he and the PRS crew for stepping outside of their comfort zone.Here's another pic of it.
As I've said before, I don't think there's any new guitar shape possible that isn't derivative of something else. To me, this looks like an upside-down left-handed guitar with an appendage to allow it to double as a boat rudder. That's not a bad thing, if that's what you are in to. It does look heavy, and it might not be the guitar to play at windy venues. But if you are attacked on stage, blunt force trauma is right in your hands.
Hey, that's a great name for this guitar - The Tremonti Blunt Force Trauma.
