Well... I'd guess that this D-Link router also has a sticker with the WPS pin on it. So that means that the same (stupid, predictable) algorithm is used in the factory for printing the labels.
Also: Even for the devices which have the PIN stored separately in the NVRAM there's no guarantee that some stupid/lazy guy didn't just copy the algorithm for label-printing used for the former devices, to generate the NVRAM-PINs for the latter ones.
