Sony's introduced a number of innovations into their latest flagship but didn't bother with the most critical issue that effects every single photo and file taken with the camera.
Sony RAW files posted on the internet today all show file sizes indicative of Sony's 11+7 lossy compression scheme.

It's a limitation of the camera/software of some kind, and I'd say it looks to me to be about the *only* remaining limitation of that camera versus the Nikon/Canon big cameras. It's really time to let this one go and let Sony do whatever they want to do. Don't buy one if it's not for you, fortunately Nikon is making some wonderful cameras for us all to enjoy that do shoot in a true 14-bit manner; no biggie.
