In articles talking about skylake, the 6700k was referred to as having a 'suggested' manufacturer retail of $350. For one it's just a suggestion (they don't have to follow that pricing) and for another low production not keeping up with the high demands created a typical demand > supply scenario which drives prices up.
Overall I'm left somewhat unimpressed. Regarding the overclocking chips both i5/i7 on skylake, they cost considerably more and left out the stock cooler for those wishing to run stock at first and oc or budget a better aftermarket cooler later. The smaller and lighter packages now also mean more product can be shoved in the shipping containers so they're cutting costs there on the backend as well making the higher prices tuck even more profit in their pockets.
It's not saying that skylake isn't a little faster but I would hope so. It's a new/improved technology. Gains were supposed to be higher, this wasn't just touted to be an incremental upgrade like 1155 to 1150, 1151 was a full platform overhaul going to ddr4 with multiple sata express, dmi 3, on and on with all the huge improvements (we're convinced) that will make this a landmark transition. Truth be told, it's really not and the improvements look more like a vanilla haswell to broadwell improvement.
Take for example hardocp's testing, they paired a 6700k with 16gb of dominator platinum ddr4 3600. That's not using some piddly bottom of the barrel ddr4, that's supposed to be some improved muscle. In cinebench haswell improved 8% over ivy, skylake improved just 11% over haswell. Ram speed from 2100 to 3600mhz made almost 0 difference. In povray haswell improved 13% over ivy while skylake only improved 11% over haswell. Same thing in handbrake, haswell had higher gains over ivy than skylake did over haswell.

These are just some basic examples of non gaming tasks but honestly skylake's improvements are looking rather vanilla/puny for all the hype. Reducing it to from what I can tell 'another typical upgrade, nothing to see here' in spite of all the major platform differences. The move to ddr4 on mainstream desktop platforms is a landmark but aside from nostalgia purposes I'm looking at performance benchmarks going ok, it's brand new, it's a total platform overhaul, it's premium priced - so 'where's the beef?'. That's why I don't see the statement of haswell being 'one step closer to the grave' holding much water. Haswell managed higher improvement gains on a similar platform with the same ram, the same dmi etc.
