Ivy Bridge-E was confirmed for this holiday season and Haswell-E was proclaimed to follow in Holiday 2014 bringing good tidings of comfort and joy (and DDR4). Broadwell, the Haswell architecture transitioned to a 14nm process technology, was expected to be delayed until at least 2015 because it was not on any roadmap before that.

Until recently when something called "Broadwell-K" popped up slated for late Holiday 2014.
VR-Zone China, the site which broke this story (machine translated), cautiously assumes Broadwell-K signifies the platform will first arrive for the mainstream enthusiast. This would align with Intel's current "K" branding of unlocked processors and make sense to be introduced for the Consumer product segment without a Business offering.
If true, which seems likely, the question then becomes why. So let us speculate!
One possible (but almost definitely incorrect) reason is that Intel was able to get the overclocking challenges at 22nm solved and, thus, they want to build hype over what the enthusiasts can accomplish. Josh Walrath, our monitor of the fabrication industry's pulse at PC Perspective, did not bother entertaining the idea. His experiences suggest 14nm and 22nm are "not so different".
But, in the same discussion, Ryan wondered if Intel just could not get power low enough to release anything besides the upper mainstream parts. Rather than delay further, release the parts as they can fit in whatever TDP their market demands. Josh believes that is "as good [of a theory] as any". This also seems like a very reasonable possibility to me, too.
Two other theories: yields are sufficient for the "K" market (but nowhere else) or that Intel could be throwing a bone to the mid-range (lower than Haswell-E) enthusiast by letting them lead. It could also be almost any combination of the above or more.
Or, of course, Broadwell-K could refer to something completely arbitrary. At this point, no-one knows but anyone can guess.
So then, your turn? Comments await.
