Indeed.The problem with small MF bodies is heat. The X1D had a LOT of early problems with heat. Even the GFR is bigger than expected (my guess is for similar reasons). Now think about the motors required for MF IBIS. They have to be many times more powerful and have much larger travel than FF IBIS motors.
Alas, physics is still a problem.

I am not sure it will be a very large problem. Piezoelectric motors are very efficient. My understanding of IBIS is that the motion is not linear, moving in the opposite direction of camera motion, but rather it anticipates certain non-linear shake properties of human grip, which is why it does not work with mechanical shake on a tripod. I also think sensor size is less of a problem as shake is not proportional to absolute magnification, but more related to angle of view/format, solving for the perception of sharpness (just as CoC and the definition of "sharp" changes with format). But I might be wrong...The problem with small MF bodies is heat. The X1D had a LOT of early problems with heat. Even the GFR is bigger than expected (my guess is for similar reasons).

I also hope Hasselblad sticks with the current form factor for the X2D, even if it’s at the expense of features. All I really want/need out of an X2D is the 100mp IMX461 sensor and a joystick for AF point selection, and suitable heat mitigation for long exposures. Hopefully they can do all of that in a body similar to the X1D.
I’d also love to see a live histogram, PDAF, and face/eye detection, but keeping a similar form factor is one of the most important things for me. Moving towards the body size of the GFX100 starts to defeat the purpose of mirrorless MF for my needs.
Well, look at how much harder FF IBIS was than µ4/3 IBIS. It took Sony years to match Olympus's performance.I am not sure it will be a very large problem. Piezoelectric motors are very efficient.

Still, Fuji thinks it can solve this problem.
I think Hasselblad is in a difficult situation here. Many people criticized them for announcing (and even shipping) the X1D prematurely. I don't think they want a repeat of that with the successor product. Fuji can get away with saying "we're working on a 100MP follow-on and here's what it will look like" without having a near-production example that people can shoot with, because they're a multibillion dollar public company with vast resources. Everyone knows that they have the capability to bring that product to market.Hi,
In my view, If Hasselblad doesn't have anything to show by this year's Photokina, they will lose another opportunity to grow, another one that will not come back ever.
Hasselblad is owned by DJI, a multi-billion dollar Chinese technology company.If Hasselblad did the same thing, they'd be criticized for showing vaporware. They're a small, privately-held niche manufacturer, and their financial status (and even their ownership) is pretty opaque. They need to show a working camera that's essentially production-ready, and they need to be able to ship it soon after it's announced.
Nobody outside of DJI and Hasselblad (and their attorneys, one assumes) knows for sure if that's true. There's been no announcement, other than the original one about DJI acquiring a minority stake - that's what I meant about their ownership being opaque. DJI may own 20% of the company, 51%, or 100%.Hasselblad is owned by DJI, a multi-billion dollar Chinese technology company.
I am certainly not arguing that sensor size is irrelevant. Obviously mass is a problem. The size of the Piezoelectric motors themselves need to be scaled. I am unsure that heat is the underlying problem though--I used Piezoelectric stages on Microscopes which would move samples the same mass as or greater than a MFD sensor. Not sure overheating was a problem, but I never really checked...Well, look at how much harder FF IBIS was than µ4/3 IBIS. It took Sony years to match Olympus's performance.
Sensor size is a problem because the light rays have a longer distance to diverge. It's the same reason DoF is shallower on larger sensors even though the required magnification is smaller.
Of course, I'm arguing theory, and practice always wins.

Ming Thein is apparently no longer with Hasselblad and he will explain it in an upcoming post (information in comments of his Z7 review)I don't think Ming is in the position to say anything, this is a crucial stage in the game and no one is going to show their cards. Ming used to give a lot more info about Hasselblad but he has really pulled back lately.
I agree that it seems more and more unlikely we will see an X2D at Photokina 2018 but everything points to it coming soon. Fuji apparently wouldn't be ready to ship a 100MP GFX until later next year either.
Very sad to hear that (too short a time to have a real influence on the companies strategy), curious to hear about his reasons but apparently some conflicts.Ming Thein is apparently no longer with Hasselblad and he will explain it in an upcoming post (information in comments of his Z7 review)

I think Fuji confirmed that the SLR type body ( increase in height ) is to house IBIS and battery and ...the body on show (apparently) was by no means a finalised type at this stage. The form factor in my opinion is more welcome than current GFX 50s type which I have been testing - at this stage I think I would prefer the R type body for my purposes in 50 MP form - I will be purchasing the 100 megapixel version as well - very similar to Leica S form factor which was fantastic for my hands.The 100MP sensor is 44x33mm, the same as the current sensor in the GFX, X1D and 645Z. So sensor size isn't the cause of the prototype's bulk. My guess is IBIS, batteries, or something else (other than the sensor) that would consume internal real estate.
