It may also be the beginning of the end for economical platforms with user-upgradable CPUs. From rumours that I read, the successor to Haswell will not offer socketed CPUs at all (in the mainstream form). Instead, the CPUs will be permanently soldered onto the motherboards. (Though Intel itself has not confirmed these rumours - at least not yet.) If those rumours hold true, then it would also be the beginning of the end for even a remotely affordable build-it-yourself PC, as the cheapest build-it-yourself PC might then cost far more money than even the most expensive current HP or Apple workstation - and anything that would be even remotely affordable would then be specced all too close to one another (extremely low performance, unsuitable for even media playback use, let alone video editing). I dread the day when we would have to spend tens, if not hundreds, of thousands of dollars just to buy into a platform with even the least expensive upgradable CPU.
Now that would definitely be the beginning of the end for desktop PCs as we know it.
Likewise, Ivy Bridge-E (to be introduced some time in 2013) will mark the end of the line for (and thus end of life of) the current LGA 2011 platform. It is currently unknown which CPUs will be available. But from rumours I read, it might be available only in its stratosperically expensive i7 Extreme form, which means a minimum cost of more than $1000 just for the CPU itself. There will likely be no economical $300-ish quad-core version of Ivy Bridge-E, and there might not even be a $600-range CPU in that series.
In late November 2012 it was falsely rumored that Broadwell CPUs would only be sold together with a motherboard, already mounted using BGA in place. Responding to such rumors that Intel was abandoning the PC enthusiast market, spokesman Daniel Snyder clarified that Intel "will continue to offer socketed parts in the LGA package for the foreseeable future."
Thanks for that. I remember that Intel had refuted it. Now, the BGA CPUs on desktop-sized boards may very well be restricted to OEMs (with socketed parts continuing to be offered to system builders).
Back to LGA 2011: Its Haswell-derived successor to Ivy Bridge-E will also use a physically different socket (the specifics of which Intel has yet to disclose) from Sandy Bridge-E or Ivy Bridge-E, as well as require an entirely new chipset just to even function.
