I had the same issue. I actually bought a Santana CE quilt top at my local GC. The color was called vintage sunburst. BTW, this guitar blows both of my Les Pauls out of the water and my Strat is just gathering dust in its case. I'll probably trade the strat for another PRS in the future.
Back to the subject: I came home and looked my guitar up on the PRS web site but it was not to be found. It also was not to be found on any other music web site. My first thought was, I've been had. I thought maybe this was some kind of a fake. I proceeded to call PRS direct and found out that this indeed was a genuine PRS that had been ordered as an exclusive to GC. My guess is they custom ordered a bunch of these to their specs and colors. At any rate, the PRS rep checked my SN and told me I had the real deal and not to worry..If I wanted another one like it, however I would have to get it from GC.
