This is from an architectural photographers personal view - but the longevity, is really under pressure here in 2025, - 7 years ago, the gap between a PO solution and the others where significant, when talking images quality, today not so much...
For my professional use I have 3 Alpa's and a full line of lenses from 23mm - 210mm and it's gathering mainly dust instead of light after the arrival of the Fuji t/s lenses, those combined with the latest Canon t/s gives me a very desirable quality - the Fuji 30mm and 110mm is performing better than the Rodenstocks on my Alpa's.
But most important, the movements and composition on the Fuji 100II is also so much, much easier to control with the movable EVF than the screen on the IQ back, especially from a lower viewpoint that I tend to use about the hight when using the waist level finder on a HB V.
So, as Paul is saying all the time, a tiltable EVF for the an upcoming IQ is very importen in 2025, in my opinion as well.
Besides the general ease of use, the fuji EVF and the 30mm t/s is the only reason why I'm using the Fuji today, since the camera itself is absolutely soulless in my view - but the camera is just working more or less flawless and the files it produces are extremely robust in post-processing.
So more mega-pixels will far from be enough for me to consider an upgrade - it's 2025 and the playing field is different than 7 years ago.
On a side note - for compensating using a soulless camera, I have been out this afternoon and enjoying some 4x5's on a Technikardan together with a "new" 300mm Apo-Symmar among others - it's a treatment that I can wholehearted recommend

Hey Adam,
Indeed, technology progresses, no surprise there - but, just about longevity:
- P1 IQ4 released October 2018, the first GFX 100 released June 2019;
almost the same number of years later, both lines still use what basically is the same sensor they did at release, the GFX had a few model iterations to fix and add features, the IQ4 a few FW updates to fix bugs and add features. The GFX had, crucially, some lenses added while the P1 did not - except for the P1 150mm recently released and for Tilt versions of the XT lenses (same glass though). The original GFX 100 had a tilting EVF option already at launch.
If I understand your post correctly, the reason for you to now use the GFX100 for your professional work instead of the Alpa all boils down to Fuji finally releasing T/S lenses, which makes a lot of sense for your kind of work since you now get enough image quality from the GFX (or better, according to your analysis of the 30mm's quality) in a much more user friendly package than the Alpas, so much so that it put your Alpas on the dust-gathering path to oblivion...
For my own work, as a B&W landscape professional photographer using a lot of long exposures, the acutance of the IQ4 Achro and Frame Averaging are the two features which locked me into Phase One. Regarding the speculations in this thread, a 150mp B&W sensor effectively makes the idea of upgrading to a 247mp colour sensor fairly meaningless, short of other changes in the supposed new IQ5.
The truly crucial point of your post, and the one camera manufacturer should pay more attention to, is how important are - for any given kind of serious, professional photography - single features which may look "the same" to the general photographers' public. For instance, I would never use the GFX series unless they come to their senses with the implementation of long exposures, which I use pretty much for every single shot and which make little sense to me in the Fuji. If Phase One disappeared suddenly and my IQ4 Achro back vaporised, I would go to the X2D rather than to the Fuji just for the long exposure implementation. Or, filter size / ease of use filters: I would never choose a system which ultra-wide option couldn't easily use a 100mm square filter system (ruling out pretty much all fixed-hood, bulbous 12-24, 14-24 kinda zooms from Canon / Nikon / Sony). And so on...
E.g., it might sound trivial to most, but one of the things I truly dislike of the IQ4 is the battery and chargers it uses.
Ab absurdum, If the new IQ5 were just a IQ4 with a new battery system belonging to the 21st century, thus eliminating the need to carry a ton of spares and a charger that takes as much room in my bag as two lenses, it would almost be reason enough to upgrade - on the other hand, if the currently vapourware new IQ5 will use the same 900 series battery, then I am not sure I'd be interested in upgrading regardless of the rest of the features... I'd just get a second IQ4 Achro (likely on the second hand market) to make sure that between the two they would last me until I die and be happy with what I got.
All that said, I have been doing some real soul-mending of my own in the last few months, using an Arca-Swiss custom-made F-line 4x5" camera non-stop every day between early September and early December for my work, and I just loved it. Loved it. There is just nothing like it. I am now developing and scanning those huge, beautiful negatives and it's pure joy.
I love digital and technology, I have been using P1 since 2010 (with a hiatus), used pretty much all digital cameras there are (except for Canon) and everything from APS-C to tech cameras (now Alpa STC, previously Arca-Swiss Rm3di, Linhof Techno, Silvestri Bicam), I used Leica (SL, S typ 007=6 and 007, and all digital Ms, plus film M and R), Pentax MF, Hasselbald film (500 series) and X series, Nikon film and digital up to the D3, Sony Nex, Fuji X100, but the temptation of saying "f..k it all" and go back to film full time, getting out of the rat race of updates, speculation, features and frustration thereof (there will never be a camera that does what each of us need exactly and even if there will be, we would still be looking for the next one!), is really strong.
Of course, I completely appreciate that going back to 4x5" or to film in general is something that not every professional photographer could do, and something that wouldn't be feasible for professional photography today for many kinds of photography. But, since I am in the lucky position of being able to do so for my work, I am seriously tempted.
Best regards,
Vieri
