It would seem that with Photoshop CC, the Finder's icon preview setting is honored rather than ignored. It made no difference whether the Finder's icon preview setting was on or off, all Photoshop files had icon previews. tif, etc files all the time (unless that pref option was disabled or save for web was used).
In the past Photoshop has completely ignored the Finder's icon preview setting resulting in icon previews for. files quickly by their generic icon rather than having to take that extra second to check a file suffix or remember file names. I generally turn off Finder preview icons because I don't really need them and it's often faster to be able to discern.
I was merely curious because there has obviously been some change between Photoshop CS6 and Photoshop CC where the icon previews are concerned. I've never seen this issue as anywhere near critical or important. I started this thread out of curiousity, not a workflow problem.
