Yes, the "D" if for "deluxe" meaning a better marker than the standard kaos. Since the kaos-d just came out, it will be a few months before anyone can make an educated statement on the differences. Personally for the price of the D, you could buy a Blitz which is electric (ramping/full auto) higher end version of the kaos.
