I guess this would not be wholly surprising. If Hasselblad were going to cut back to the bare essentials, the classic CWchrome is the one that would sell the best of the three...
I had emailed Hasselblad about this a few months ago. They said that they 503CW in chrome will continue in production, though they other bodies were being discontinued. They wanted to keep one "legacy" body in production they said. It could all be marketing crap as well, I don't fully believe email response from companies
