That is a good point, but it sounds like Coffee Lake S-series chips that are 65 Watt TDP will likely be quad-core. The 6-core models will be 95 Watt parts most likely.My opinion, I consider Intel Kaby Lake dead; upcoming Coffee Lake increases core count throughout the line-up. I wouldn't consider scratching a Kaby Lake itch,
Except Core m, which will likely remain 2 cores, transitioning to 10 nm Cannon Lake at end of year (Intel target).
On the Mac side, they usually have two i5 and one i7 27" iMac model. The two i5 machines are 65 Watts, and the i7 is 91/95 Watts. This time around I went with the slowest of the three. I suspect even if Apple were to release 6-core iMac with Coffee Lake, it wouldn't be until 2018 and we'd again have the entry level and mid-tier machines being 4-core, with the high end machine being a 6-core i7 for about 20% higher cost. (That's overall cost, not just CPU cost.)
I'm just guessing of course, but that's how I see it playing out, and given that scenario I don't feel like waiting another year, esp. since Kaby Lake ticks off the other checkboxes I was looking at, including hardware 8-bit and 10-bit HEVC and VP9 decode, as well as hardware 8-bit and 10-bit HEVC encode (and 8-bit VP9 encode). Also, for fiscal year related budget reasons, it makes more sense for me to buy it this year than next.
The other thing I wonder about is single-thread clockspeed. How highly will the 95 Watt 6-core parts be clocked when compared to the 65 Watt quad-core parts of the same general class?
Note however, I say this as someone who is coming from a Penryn MacBook Pro and a Lynnfield iMac. Mind you, the last time around I did take your advice. I waited until the iMacs got quad-core options and then eventually bought one. The i5 model iMacs of that period were dual-core, so I splurged and got the quad-core Core i7. For my usage though, the jump from 2-core to 4-core was pretty significant. The jump from 4-core to 6-core will likely be less significant. It should also be noted that at that time the dual-core parts were much higher clocked than the quad-core parts, although I don't see that happening to anywhere near the same extent this time around.
