Martin has added a 000C David Gray Custom Edition to their website that was not previously announced. Martin often makes 'Limited Edition' guitars i.e. guitars with a musicians signature on them. It's assumed that the artist had some input on the design of the guitar, though this varies widely.
I'm not exactly sure what the difference is between a Custom Edition and a Limited Edition. These are usually announced at NAMM, which was back in January....no idea why this one wasn't announced then.
The David Gray is a 000-14 Fret Cutaway. I like David Gray, but not enough to buy a guitar just because his name is on it...and not enough to buy a Martin cutaway :)
