Yes, everything old does become new again, if you hang out long enough. I have already. For instance, I was around at the end of the older era when cars were being shot with tungsten bounce light off giant studio canvas "tabs" or "bounce flats" and coved stage walls. Then, briefly, the in thing for a few years was to replace the tungsten light with that of multiple very powerful studio strobe power supplies, employing many flash heads. Then, the next trend was to shoot them with giant soft boxes in which were placed those same multiple flash heads. Then, the next one was to replace the flash heads inside the boxes with tungsten light fixtures. And finally, the best solution was thought to be to once again to shoot them with tungsten bounce light off giant studio canvas "tabs" or "bounce flats" and coved stage walls. There always have been alternate techniques (as are being employed right now) used at any given time which are different from the general trends described above, but that is a pretty good summary outline of studio car lighting technique, circa 1962 to 2012.
One contrary fact, as for bokeh, taken here as to be shorthand for actually the very narrow depth-of-field look afforded by lenses which are sharp at very large aperture settings (given the focal length and format size), shot at or near the maximum aperture, its use is far from universal; it's mostly employed for things like portraits, weddings, lifestyle, some food shooting and moody environmental images. Even conceding the "bokeh" trend, you might want to keep in mind that in 90% of all hardcore photography of manufactured products, maximum depth of field never went away and is still the presumed method of operation. Again, exceptions abound, but I'm referring to the rule, not the exception. I, myself love to introduce the narrow DOF look in some feature shots, and they're usually well received in those instances, but, as for the "hero" shots of these products, clients don't want to leave very much to the imagination of potential customers as to what their industrial designers have labored over for so long.
So to summarize about the narrow DOF look, yes, this too will come to pass. It's just a matter of time.
