So, does it hit ALL the right notes? Or are there a few wrong ones???

Read through this review if you haven't already: http://www.guru3d.com/articles-pages/asus-radeon-rog-rx-vega-64-strix-8gb-review,1.html
AMD has no voltage regulator so they put their cards on the market overvolted resulting in higher than required wattage.

This is not correct. All Vega boards - even AMD reference designs - have voltage regulators of course. Aux power connectors to GPUs deliver 12V, you'd fry your silicon to cinders in a millisecond pumping that level of DC into a GPU...
As standard, Vegas do run on comparatively rather high supply voltage, mostly because Global Foundries (AMD's chip supplier) doesn't have a modern high performance silicon process at the moment, so they're pushing a low-power process beyond its comfortable design parameters by pumping up the volts, leading to very high power consumption. This will be remedied when Global Foundries moves on to 7nm process next year.

Something is really screwy with that review. In most tests the Strix is either dead-on performance-wise with reference design Vega, or actually even SLOWER - which really is impossible, considering the vastly more capable, 2.5-slot cooler of the Strix version.
Hexus' Strix Vega review is much better, and much more accurate to the real thing I'll wager (meaning it shows actual speedups due to much more temp headroom) - Guru3D must have received either a dud card or one that has done the rounds amongst several sites already and been pulled apart repeatedly and not put back together particularly carefully again.

See my above links for the Guru3D reviews.
Guru3d did an earlier review but took it offline 06Sep2017 - ASUS requested their sample back and requested the review be withdrawn/suspended because (for whatever reason) their media sample card wasn't the final production version, had wrong VBIOS, and was still a "work in progress".
Guru3D posted a revised review 25Sep2017 - noting in the introduction that they weren't able to comprehensively test a "final revision" sample so some of the benchmarks and observations were based on data from their earlier review.

ASUS should have sent guru3d another card so their excuse could be corroborated. They're not doing themselves any favours.
Matter of fact, looking at the Hexus review doesn't exactly fill me with a sense of elation. Marginal fps gain at higher wattage isn't exactly the sort of trade off I was looking for, especially since the temperature is reduced by 10 degrees C. And we've yet to establish performance based on pricing.
I am hoping the reason ASUS delayed their RX Vega release was to rectify some operational issues, as opposed to the availability (or lack thereof) of HBM2. And I'm hoping there will be little issue with undervolting.

ASUS may have been among the first to unveil its custom-design Radeon RX Vega 64 graphics cards with the ROG Strix Radeon RX Vega 64 (model: ROG-STRIX-RXVEGA64-O8G-GAMING), but kept its clock-speeds under the wraps. The company updated its product page, revealing the clock speeds. Out of the box, the card is clocked at 1298 MHz core, with 1590 MHz boost, and an untouched 945 MHz memory, against AMD-reference clock speeds of "up to 1546 MHz" GPU clock for the air-cooled RX Vega 64. It still pales in comparison to the RX Vega 64 Liquid Edition SKU, which ticks at 1677 MHz core and 1750 MHz boost. The company is yet to update the product page of its ROG Strix RX Vega 56 O8G.
