No not Premier, it's an Intamin, and it looks like this one is the same. So a new Intamin is going to KD.
It's a newly developed track system that Intamin have created to get an even stronger and stiffer track then the quad, to have longer distances between the supports, which means less supports, to make the manufacturing and ride cheaper.
I also have a feeling that this dual spine track is a lot easier to manufacture then quad-rail as well.
So no this is not a new Premier, pure Intamin awesomeness...
