I don't think the camera proves anything of the sort.
What you do have is rather big questions about Sigma's marketing. To my mind, to date Sigma have relied on a core group of dedicated fans to make all the positive noises about Foveon. These people have an emotional connection to the company that has allowed them to ignore/excuse the drawbacks of Sigma products. Where the rest of the world laughed and scorned, this group soldiered on content the benefits outweighed everything the mainstream had to offer.
There is genuine loyalty in this group. The expectation about the Sd1 was very high, fueled by Sigma itself (and users with close connections to Sigma). The launch price has dashed those expectations and soured even the core group's allegiance. They feel their long suffering loyalty deserved a reward and it looks like Sigma marketing have chosen to turn away from them.
Hardly surprising there is such an emotional backlash. Perhaps with time, emotions will cool and more realistic heads will come to the fore. Perhaps, the fans will get over it and gradually return to the fold (even if they don't buy the SD1). But perhaps they won't. Sigma marketing are gambling heavily.
For me, no matter how good the SD1 turns out to be once the dust settles, this move merely confirms everything I have thought about Sigma (rather than Foveon) since day one.
