We aren't talking games though, we are talking Desktop. The prices isn't driven by the 'K' series, it's driven by the other SKU's, and market share isn't gained with Enthusiast it's gained and sustained with the millions of Dell/HP/Lenovo systems that are shipped worldwide every year. On the face of things it is easy to think that gamer and enthusiast generate huge sums of money for Intel but it's not the case, in Q1 alone this year they were running at nearly €15 billion, at crazy margins of over 60%!!! The majority was though their Client Computing Group which incorporates the enthusiast market, but also all of these other desktops, which accounted for $8 billion of that $15.
Look at the AMD Athlon 64 as an example the £100 3000+ that came out in December 2003, it took Intel way too long to respond all the way until Q3 '04 when they took anywhere from 20-35% off the higher end models, it was more common place for that to occur, since these days they just replace the range, and a new chipset/socket and forget about the old ones. Well AMD aren't operating under that banner, they want to keep the old model of sustaining a socket as long as possible, giving access to ever larger range of products a significant price ranges from the super low end, all the way up, this in itself will cause a headache for the people over at Intel, since they have to consider a counter to this, OEM's build boards, on the same socket for years, with little R&D cost, just drop in a new CPU... what's not to like if you are big business?
TL;DR
Intel will almost certainly be forced to reduce prices, and in turn the enthusiast prices will drop along the way.
Very valid points, they certainly don't seem worried at the moment however.
