Considering the platform they released for Skylake, I wouldn't expect it to go beyond four cores. They've pretty majorly shafted it on the chipset side of thing, it's well below the X99's maximum output. I expect you'll have to wait for cannonlake to see a serious entry in the skylake architecture. The enthusiast market is all Haswell/Broadwell refresh for next year, the X99 chipset has all the bells and whistles right now as far as future proofing goes. The die shrink will let them do a lot more with the Skylake architecture, hopefully, and they'll put out a proper enthusiast chipset to go with it.
