As noted before really a moot point as the 16 bit file is one the main advantages of the IQ100. I don't believe it was ever official, but even if it was, the conversion was not that good even on the 14 bit files. I saw it mentioned months ago on that you could open the 14 bit files and I tried that, but did not find the conversion was very good and LR at least still had some errors with seeing the 14 bit files to import. Both on Mac and Win systems.
