Why? An 8-core steamroller would be the exact same chip/die used for opterons and the server roadmap only showed "warsaw" piledriver based chips throughout 2014.
Some people think that there may be a piledriver refresh of some sort for AM3+ with higher clocks, better turbo or even a 6 module/12 core piledriver. And that's basically
the end of the line for the socket.
FX is not
the same die used in Opterons.
Opterons have Quad channel memory controller and four HT Links. These are features built into the CPU die itself, not something you can just add as an afterthought. FX doesn't just have these disabled like Intel's Extreme chips, they straight up don't have them.

I do, but your filling in the gaps perfectly and I appreciate that.
Now If the GPU on the APU is connected to the with PCI-e lane instead of a ring type bus I am assuming that can be gimped as well as the onboard NB and therefore those dies can be packaged for AM3+.
My main concern is the fact that All I have been able to learn has pointed the fact ONLY Kaveri Die's will exist from steamroller. I hope all this info I've been seeing is incorrect but with the new CEO's statement of AMd getting out of the High performance market it looks pretty clear to me that that will be the case.
I am just hopeing if this is in fact the case that the arch will allow for am3+packageing of the Kaveri die's and therefore AMD will see the benefit of releasing Kaveri's chips to fill that market.
I really think it speaks volumes that there is no Codename for steamroller discreet chips.
It is connected by PCI-e, and normally that would imply that it could just be moved, but something to remember is that APUs have no HyperTransport link. The chip itself has no way to communicate with the Northbridge on an AM3+ motherboard.
This isn't something that can be half-assed, this is something that needs to be built into the CPU die itself and sold that way. Unfortunately, to do so would be to create another CPU die entirely that could not be used in FM2, and so we're back to the current logic that we would need a chip that is made for AM3+, and if it can't be used in FM2, why add a GPU at all, just make an 8-core.
The designs are too different, it would be like asking Intel to put 1155 CPUs in a 2011 socket, or ARM in a 939. They're incompatible by design.
Anyway, we knew very little of Vishera too until right before launch, though we knew plenty about Piledriver, and with even Kaveri delayed until 2014, we aren't even close to launch. So the lack of info (while it does annoy me) doesn't bother me. It also makes little sense for them to skip on making an AM3+ chip since the heart of their work, a Bulldozer based module, is used in all 3 segments. The only work they would have to do (man I make this difficult job sound easy huh?) is literally take a 8350 and swap the modules. Maybe a die shrink. The entire point of the new FX design was to be highly scalar and modular (ha) after all.
