I've followed the development of the Hasselblad X1D since it was first announced, what, a half dozen or more years ago?
It is a superb camera, more equivalent to the Leica SL than any Leica M in form factor and workflow. I rented one for three months (the X1D II) and loved working with it.
But: There is absolutely no way it actually competes with a Leica M, any Leica M, for being a handy, compact "leicht kamera" for general purpose photography. Having had both side by side for three months, the user experience is utterly, totally different, the 'Blad lenses are huge, the operation of the 'Blad is much more measured in pace. The range of available lenses (all excellent, btw) is fine but the options are much more limited, particularly now that the M has Live View when you need it.
In use, the Hasselblad X1D II (now much more a mature camera than the original X1D with first gen firmware) is much more akin to using a Leica SL than any Leica M. I had the SL: it was a magnificent camera, but ultimately it is a larger and heavier kit to cart about than a Leica M, and I pretty much stopped using it when I retired, switched to the M and CL cameras. This is why I was reluctant to buy the X1D II after enjoying using it so much, and I have the same reservations about the X2D for my uses. I bought the Hasselblad 907x as it addresses my desires for a medium format digital camera more appropriately, and its back is completely compatible with my existing Hasselblad V system kit.
I'm more than happy enough with my M10-M and the 907x. They are completely different animals in use, and are significant for very different kinds of photography.
