The Potbelly series has been available in Japan as a standard ESP model for quite a few years now, but the Ltd PB has only recently surfaced. They don't really do it for me; the shape looks a bit "generic PRS-deriviative" to my eyes. I bet I'd change my tune if they made a black one with block inlays and gold hardware though. "Black Beauty" cosmetics always look good on any guitar.
Edit: not that lazy, are you, LazyNinja? Beat me to it anyway. :D
