#2Hopefully it will be the the first to offer the much cheaper AMD Ryzen/Naples, too.

#3I think it's funny that big Xeon upgrades seem to always occur approximately 8 months after big Power architecture blog posts.

#4It's been awesome to see our Skylakes rolling in over the past several weeks. I personally have been waiting nearly 10 years for AVX-512 ever since playing with LRBni.
Disclosure: I work on Google Cloud (and helped a bit in our Skylake work).

How much confidence do you have that Rev. A Ryzen parts will even work?

That's a bit too extreme, don't you think? Disliking AMD is one thing, but claiming that the entire initial run of an AMD processor might be faulty is just silly.
My guess is that you have no idea how much effort goes into verification and testing of something as complex as a microprocessor. A significant chunk of NRE costs goes into verification and test AFAIK.

In fairness, there's precedent.
Though that was the FPUs in Intel processors, not AMD. So it's not very good precedent.

Around 80-85% is the projected cost of Verification and Validation (pre/post - Silicon). This is what historical data shows for us (as a CPU design firm doing ARMV8)

Intel's FDIV bug was an outlier. Besides, nowadays most of the ISA is implemented in microcode[1]. There are two advantages to this approach: 1) it is much easier to verify the microcode unit (it's simpler/smaller), and 2) it allows CPU vendors to "fix" ISA implementation issues post-release by issuing microcode updates.
[1]: ISA => microcode is equivalent in some respects to C => LLVM IR
