The new camera is likely to be a full 24X36 frame. Let's dub the product "The Xpro 36". Offering 36MP without altering the X pro 1 pixel pitch.
The resultant chassis will require much larger energy storage and CPU capacities (The X Pro 1 already a wattage challenge).
FUJIFILM isn't fooling around here. Digital imaging leadership (Where Panasonic has excelled with MFT) is their only avenue to sustained prosperity with film (regrettably) on the wane.
A whole new set of Fuji AF FF lenses and filters becon...not to mention the new printing opportunities. Of course the M lens hoarders will be delighted.
After carefully examining the planned INITIAL X Pro 1's under performance "upgraded" via ver. #2 firmware release today, we can easily observe FUJIFILM's strategy unfolding. Release then "upgrade" that which was good in the first instance.
The lasting result is enhanced customer credibility and faith––a precious commodity these days.
Look at the new lenses (e.g., 14 f/2.8). The MTF's are stunningly good.
So much so that we might see the Kings of Lens design no longer reside in Solms. The idea that a rear element architecture positioned close to the sensor can sharply reduce vignetting is compelling––especially in wide angle lenses.
Moreover, with patented FUJIFILM demosaic detector science eliminating Bayer AA filters and their quirky magenta stains, CA and high contrast edge colorations, we may be seeing the end of an era for the camera companies who haven't properly tended their intellectual property. The Bayer algorithm appears effectively obsolete with the release of the X Pro 1.
Recall that of the ten leading vacuum tube makers NONE participated in the transistor revolution (Chet Rayhmo–the "R" in TRW). Nikon, CANON should be concerned.
