I'm going to jump in with my first post here and throw my theory out there.
That could very well be a rosewood. I have a couple of small pieces of Bolivian RW that has similar dark and light chocolate striping to the picture. It could be Brazilian RW, too. Most of the East Indian RW I've encountered was very purple, but I wouldn't rule it out, either. I don't know how Dean makes their guitars, but I would suspect it may be a veneer, at that, since there doesn't appear to be a lot of "deep carving" in the curves and contours of the top and back.
I'm inclined to say that it's not Zebrawood, as it has more contrasts between light and dark striations.
Just my thoughts.
