My motivations and goals for buying the 907x, aside from the fact of the special edition being a commemorative piece honoring the Apollo 11 Landing event, seem a bit different from just "wanting to buy a digital camera."
The 907x/CVFII 50c revitalizes my Hasselblad 500CM kit with a full digital workflow, using the back alone, at the same time that it gives me access to the X, V, and H system lenses on the 907x. I prefer the 907x over the X1D model line because it is primarily a waist level/tripod camera rather than a camera oriented primarily for eye-level work ... similar to why I love shooting with the 500CM so much. The 907x/CFVII 50c also continues the modular tradition of the Hasselblad V system cameras, something that I've been delighted by for decades.
When Hasselblad announced the 907x Special Edition, I didn't have to think about it or wonder if it was a fit. I knew immediately that this was what I'd been waiting for and placed an order immediately. For me, an X1DII is not a potential additional body for the future, if I find that I want/need more of an eye-level camera with the same sensor dynamics that can use the same lenses.
Should Hasselblad have come out with the two parts of this kit separately over a year ago? That's a value judgment that I cannot make ... I'd certainly have enjoyed getting the kit earlier than I did, but I don't know what business and manufacturing challenges Hasselblad has been striving to overcome well enough to make that judgement. I know that it would not have changed much for me and my purchase decision. I'm just glad they decided to come out with this kit at all. The 907x body provides a way forwards into the modern lens line, past the V system but with a lot of the same feel and ergonomics.
Regards the Speedbooster adapter that Richard would like, well, in some ways it would be nice. These devices are never lossless, though, so if someone produces one I'd have to evaluate it with some care. But my lens kit just happens to be equally functional on both 6x6 film and 33x33 (cropped) sensor by just dropping down one focal length in the range, and supplementing it with an additional, wider focal length in XCD mount. That works well enough for me, too.
