Skylake and Broadwell-K at the same time doesn't surprise me. I suspect that Skylake will still be more expensive, possibly because of DDR4 and various other improvements so that it will practically be the high end choice, competing with Haswell-E.
Or I could be wrong...
You can be sure that Skylake-S will be cheaper than Broadwell-K. Also Skylake-S supports both DDR3 and DDR4.
