With the iMac Pro freshly minted, I think Apple will try to squeeze at least one more speed bump out of the current iMac chassis, if not more.
For the regular iMac, that probably means Coffee Lake, and with the i5-8500 supposedly due in February, it appears that all but one of the 8th gen (8700K/8600K/8500) equivalents of the current processors will have hit the market. There doesn't seem to be an 8600 to speak of, but Apple could go with an 8600K/8500/8400 lineup.
All have six cores, albeit with slightly lower clocks and slightly more heat/power consumption.
Despite that, single thread performance is roughly the same, if not slightly better, but multi-threaded tasks benefit from the two additional cores.
I've been planning to order one of the mid-2017 models, but can afford to wait another five months.
Had CL been yet another ho-hum update from Intel, I would have by now, but the two extra cores have disrupted that plan.
I guess a lot depends on whether the flurry of new models that Apple pushed out in 2017 means the company cares about the Mac again, or whether it was more of a fluke, and it will let them languish again, like the Mini still does.
