I think, unfortunately, that this is really a sad story of private equity ruining a good business by starving the photo business of internal resources because other business areas seemed to be more profitable from an internal perspctive (C1, B2B drones, aerospatial).
1) We never got AUTO LCC - when the XT was first marketed, it was insinuated that the metadata could be used for more than just vignetting correction, e.g. internal LCC profiles
-> The excuse was that its more complex, that you need to factor in aperture, bla, bla, but I am convinced they just spun off C1 and then internal at arm's length invoicing was implemented and the result was that there was no money for fancy IQ4 features because everyone thought we better let the C1 programmers work on building a Lightroom killer - ie compatbility with Sony, Leica, Canon, Nikon foremost and "consumer wants" like pano stitching etc.
2) The IQ4 has stopped development following a bit the theme of milking a workin system and putting all cash into other business areas
They never even bothered updating the IQ4 to an IQ4+ with improved I/O (battery life, wifi, etc. are a disgrace compared to what's possible today).
I hope they really go the full nine yards and up the ante on every aspect, across the battery system, I/O, internal processing, etc.
They should also make whole early XT buyers and offer fair upgrade pricing and skip profits on this aspect.
