That is why I am putting out the theory that:
1. SR FX can not be made somewhere for whatever reasons (yields, no SOI, etc) so AMD has to stick with smaller cores (6800k is 246mm^2 when FX 8350 is 315mm^2, 6800k SR replacement should be smaller than that because of the transition to 28nm from 32nm
2. AMD no longer has a reason to push their chips from server into desktop. Their x86 CPUs in servers are a complete joke at this point and completely uncompetitive. Last I heard they were getting ready to drop below 4% market share in servers. Meanwhile, their HEDT market share is growing. Meaning that to focus on a market you're not winning in with x86 cores and then letting your work in that market trickle over to the one that's actually performing well is wrong. Hence, I expect AMD to break from their traditional make a server die an HEDT chip and instead just make a HEDT chip and let it trickle over to server if it needs to because the microservers aren't pulling their weight.
3. Therefore, AMD's lack of big x86 server chips could be due to AMD not trying to save a sinking ship as well as GloFo 28nm simply not being able to support a large chip. So, AMD would try to offer something new (HSA, microserver) instead of trying to compete directly with Intel in server space by offering power efficient big x86 cores. Does "we're not going to compete with Intel" ring a bell now?
4. Because of 1., AMD is refreshing PD to fill the "traditional" role. I remember it was referred to as being kept around as a platform for those who need to transition, but it was just assumed that it was for people who are waiting to transition to APU platform. It was never even considered that it is a transitional part that leads to a brand new HEDT/Server platform.
5. Before you go "but how can AMD release a faster HEDT chip if they're not competing with Intel anymore!", realize that Intel has stopped going for that market a long time ago. Their high end parts are just a large number of mobile-optimized cores thrown together.
