Well, that's awkward. 

They're nothing more than a couple of pics or so of the case with the words "it's got a soul" and "it's got a brain". There's not much to study.

Actually. You would be surprised. (I checked out the new info.)

What we do know is the chip is monolithic. The size is about 530-560mm2. Titan X is 471mm2. That's almost a 15-20% larger chip.
Titan X had roughly 12 Billion Transistors, so Vega should be a good 14+ Billion Transistors.

Other information we have gleaned is that it uses two PCI-E power cables, so it's using 150w or more power.

The HBM2 memory is 2.5X larger than HBM1, interposers don't get much bigger. The HBM2 memory is twice as fast, has twice the density as HBM1.

All in all Vega is gonna be big, expensive and probably consume a ton of power.

The new NCU features are already known, so I won't touch upon them.

The real Question is... How will Vega stack up against Volta or Pascal refresh?

Hmm

About a month ago Videocardz published an article with a blurry pic of a Vega board with the power connectors exposed. It had a pair of 8+6-pin power connectors:

The engineering samples use at least 225W of power.

As for the size, we have to go one more month back, when tech sites made articles about Vega's architecture. In those articles, some sites had a pic of Vega in the hands of Raja Koduri. Using that pic, Videocardz made another article trying to calculate the size of it

Their conclusion or estimation, was that Vega was between 520-540 mm2. Not too far from the numbers you've seen, and still smaller than Fiji.

 

With all that said, it was a no brainer that Vega would be bigger (and therefore more expensive) and use more power than Polaris. The question is how much.
