I was holding off ordering the X1D until I saw what Fuji had to offer and now I think I'm going for the Hassy.
Reasons:
This is to be a lightweight travel MF capsule system for me. Most important is the 24-70mm range which, with the new lens Hassy announced today, is now covered. What I really value is the svelte form factor and low weight and you'll notice that Fuji haven't announced a weight for the GFX - and I'm guessing I know why: this is more a competitor to the full fat MF systems we have already but without the swappability.
Also, the FPS, whilst allowing the higher shutter speeds, will also introduce the risk of shutter shock. And add to the weight. So for me the trade off of lower maximum shutter speeds for smaller form factor and weight and less risk of shake is worth it.
I also don't want to build a big system around this for my use-case. And, as I get older, I want my cameras to have some 'thingness' - which the Hassy looks like it has in spades and which the Fuji looks like it lacks. The Sony A7RII is most of the camera I ever need but it feels like a computer - whereas the Leica Q feels like a camera.
Despite that I'll be trading in my brand new replacement, not even un-boxed or used Q* agains the Hassy because even though I love it, it is slightly too limiting.
We all have different logics in choosing gear and mine aren't in this case driven by commercial logic but by desire: desire for smooth tonality, high DR, 'thingness' and light weight. Desire for something different. Desire for something bloody expensive.
* a long story: it's a passport replacement but the passport expired just as the unit was replaced.
