I'd easily pay triple the price of an X Pro 1 proportionately sized up to accommodate a 36mm X 48mm (or larger) new Fuji sensor. Same styling but no video or special abilities required like 12800 ISO, more than a couple frames per second or face recognition. I can recognize faces just fine thank you, even remember where I was when I took the image (skip GPS) and even focus for myself if need be. No folding tray LCD screen either.
6000$USD for the body and 950$USD each for 35, 70 and 100mm 2.8 prime lenses.
A lot of what makes the X-Pro1 what it is, is the CMOS sensor. Even if you strip away high ISO & video & 6 fps shooting, you can't have a useable hybrid/electronic viewfinder without the fast readout of CMOS.
So if you want a "36mm X 48mm (or larger)" version, we're back to the age-old question - why are there still no medium-format sized CMOS backs/cameras? And the answers always come back: it's about semiconductor fab processes, steppers and stitching. Fuji would first have to crack that - but if they do, they will have the potential to revolutionize and own a very large segment of the MF digital industry (supplying sensors to the back makers, if nothing else); and I'll be celebrating like a maniac.
BTW, I love two things about this X-Pro1 sensor:
1) What they've done with the new, more random 6x6 Bayer array; they claim there's no moire even without an AA filter. Very clever; kudos to Fuji.
2) It's suitable for
deep-sky astrophotography, straight out of the box!
It actually transmits a decent amount of H-alpha 656 nm (the red colour of nebulae)...which is even more remarkable when you consider that the ratio of red to green pixels is down by 20% compared to a "normal" RGGB array. I was gobsmacked to see an example of a tracked deep-sky photo which shows this, in the Fuji sample pics:
http://www.fujifilm.com/products/digital_cameras/x/fujifilm_x_pro1/sample_images/img/index/ff_x_pro1_001.JPG. They actually bloody care about astrophotographers enough to use this as a selling point! (The 18mm f/2 wideangle however has pretty strong off-axis aberrations, at the f3.6 stop this shot was taken at; and it's been oversharpened too. But I'm sure the other lenses are better, and I'm sure an adapter industry will spring up for the X mount).
6000$USD for the body and 950$USD each for 35, 70 and 100mm 2.8 prime lenses.
A brand new, fast 35/2.8 medium format wideangle for $950? As much as we'd all love it, I can't see that ever happening. $1950 at best, if the Mamiya 45/2.8 "D" is a guide; and let's not even think of using the Leica S2 35/2.5 (north of $7950) as a guide!
