Sigma DP2 Merrill marketing: Hyped, wrong, dishonest, or just defective cameras?

We've seen some demonstrations of extreme levels of internal lens reflections in THE new Sigma DP2 Merrill that produce unusable images any time the sun is in the photo:

The lens flare caused by internal reflections is most obvious in high dynamic range scenes, where there is a lot of brightness in a single point (the sun). However, the problem still exists when the lens flare is not visible, and it reduces the contrast of the image with extra random light striking the sensor without forming an image.

Sigma marketing announced the following about the new DP2 Merrill lens:

Unlike the SD1 ... the DP1 Merrill and DP2 Merrill each boast exclusively-designed, high-performance fixed lenses. ... and include “F” Low Dispersion (FLD) glass to correct abberations and Super Multi Layer Coating to reduce flare and ghosting.

Since the lens flare is far worse than is expected in most high end modern lenses from other manufacturers, is it possible that some of the new DP2 Merrill camera lenses are defective? If they're not defective, then is the lens marketing dishonest, innocently wrong, or just hype that should be ignored? In other words, can Sigma marketing be trusted to inform us of what we should expect when we buy their products?
