HOWEVER, what gamers want is a decent priced (sub 200 dollar) mainstream i5 with SIX true cores.
6 isn't enough of a jump over 4...
For most home / personal computing (including high end video games) diminishing returns kick in hard past 4 cores. The problem is that in the few cases where tasks can be easily subdivided so as to utilize more than 4 cores, the cores will normally be stuck waiting for memory updates which continues to lag (speed / throughput wise) behind processor compute ability at an increasingly large gap which spans orders of magnitude. Of course the only known way to speed DRAM is to utilize more power, which goes against the general IT development trends (greener computing, more capable mobile).
The processor to memory speed gap is one of the reasons why Intel is investing in novel memory technology (phase change memory, etc.). The recent XPoint memory announcement hinted at potential future usage as "page swap" memory, replacing virtual memory management swapping pages out to disk (mechnical or solid state).
I haven't read all of Intel's releases this week, but one area I'm interested in is seeing how eDRAM (embedded DRAM) aka Crystal Well technology is going to end up being available and utilized across the Skylake line. In memory intensive benchmarks eDRAM has already shown considerably improvement in memory constrained benchmarks in Broadwell mobile processors, wheere it acts as an additional level of cache.
Give me 8 true cores and 16 threads, remove the IGP which I don't need for such a CPU...
Most people don't utilize more than 2 cores for more than 25-33% of the time, so the market for consumer-oriented many core processors just isn't there. People who really need the performance already just buy a Xeon.
Intel's "hyper-threading technology" is one of the biggest disappointments in many years, I wish they would let the branding and feature set die in obscurity like it deserves (IMHO).
Yes, yes, I know, Xeon and Haswell-E, but the reality is that the "need" for 8 core chips won't really happen until more of them hit the desktop market, and what AMD sells as 8 core doesn't count.
Well 8-16 core processors have been around for what, a bit less than a decade now? They won't really happen in the consumer / desktop market, because the market isn't demanding it (with purchasing dollars, not wishful thinking). Look at the very modest take-up of the Haswell-E X99 (LGA2011) 6 to 8 core processors released last year (August-Sept 2014 IIRC).
I love fast computers, personally I have a 6 core i7-5930K, and the performance difference for most home/consumer applications is so trivial that I don't notice a difference over using a 4 core i7-4790K except for in parallel benchmarks.
