Is this confirmed or rumor? I have never upgraded a processor so It wouldn't bother me too much as long as it doesn't raise prices. It would make extreme OCing potentially more dangerous and I make others more cautious about buying cheaper boards.
I do not think we will see a die shrink to Haswell in a desktop socketed processor form.
Tocks will be socket/soc, Ticks will be SOC only. So Haswell will be Socket/SOC, Broadwell will be SOC only, Skylake will be Socket/SOC.
Makes sense as the focus on ticks is for mobile improvements overall and the desktop does not benefit that much now from ticks. I think Intel was disappointed with Ivy Bridge desktop sales. The CPU hardware is far ahead of the software on the desktop.
Fact or Rumor? As of a couple months ago Intel had not made a final decision, but what is outlined above seems to be the direction it was going. I am not sure of where that decision is today. We will likely know more after CES time frame.
