Without the desktop CPUs being made for the general pop, we will fail. We are not a market.
There is no reason to put more money into expensive designs if only very few computer enthusiasts that are going to buy your products.
This is probably much further into the future, but I do fear the removal of the computer enthusiast market to a large degree.
As you say, 'computer enthusiasts' are not a market.
In the grand scheme of things, Intel 'K' chips are a miniscule product volume within their entire processor lineup... it's the other models, the non-K i3s, i5s, Celerons, Pentiums, and i7s that make their way into the hundreds of millions of corporate desktop client systems, 'standard' consumer systems from the big OEMs, etc ... that is the market.
With gaming being increasingly dominated by consoles, especially with the new consoles being released within the next year or so, and the millions of people buying and playing games coded for their ARM devices, it's entirely possible that any 'enthusiast' system of the future (if you want it to be the best of the best and fastest possible) will be, essentially, a low end workstation.
That being said, I think that for gamers, building a custom PC with over-the-top everything, the embodiment of gratuitous conspicuous consumption, will slowly decline.
If there is less of a desktop market, in the future, there will be less custom and gratuitous 'crap' for 'enthusiasts' to ooh and ahhh about and use. If that occurs, the 'enthusiast' market will be small, niche, and utilize 1P and 2P workstation components, and be a much more expensive choice than today.
General, everyday computing will move to ARM or mobile Atom based systems.
