I disagree that they're 'missing a trick'. I believe that the cost of manufacture for the 907x body is trivial, and the price-add to sell the CFVII-50c with it only as a bundle is also trivial. The V system accessories and lenses are all discontinued, so selling just the back permits nothing more than the existing community to generate profit from the back for Hasselblad. Market data shows that most of the profit generated from a system camera to the manufacturer comes from the sale of new lenses and accessories, and most of that within the first 18 months of ownership, so if they sold only the back, it would be one shot at some profit from their existing audience and little more. Those owners who only want a digital back for their existing V systems already have a host of options when it comes to buying a digital back...
By selling the CFVII-50c back bundled with the 907x body, they open up the field to existing Hasselblad V system owners to buy new H and X system lenses, adapters, and other accessories. As well as other X system bodies to use with them. Many might not, but I believe that the greater number (similar to myself) will. I had no real ideas to buying more than the 907x/CFVII-50c, and XCD 21mm lens (to have the FoV equivalent of the SWC/M with the digital back) when I ordered the 907x, I was going to use my 500CM system with the back otherwise. But I found the lenses and the 907x compelling enough to put my money there. And the 907x/CFVII-50c kit was already about a third the cost of the previous CFV-50c back kit.
To me, it just makes more sense
for Hasselblad to sell the back as part of a kit that invites users to expand their Hasselblad system with currently offered product.
Special editions are something that virtually every camera manufacturer does, and they're there only and specifically for those who value what they commemorate. They rarely cost much beyond the base model to develop, and the price premium charged for them pays that additional debt off if the edition is popular. I see no downside to them, other than that (to me) they are sometimes a bit on the silly side. A "Hello Kitty" version of a Leica? Laughable when it was introduced, now an amusing and funny special that some folks really like.
The only accounting for taste that makes any difference is done by the person deciding to spend their money.
