AMD Vega 10, Vega 11, Vega 12 and Vega 20 Rumors and Discussion
"Because the game drivers aren't ready yet" would be the obvious answer

There was no need, TitanXp has just a small performance bump over TitanX Pascal, which already got sent to every major media outlet at the time of it's release.
Note that AMD themselves are providing and linking to game drivers for the FE dated 6/27

32 bytes for GDDR5 and HBM2, 64 bytes for GDDR5X.
HBM2 does support Pseudo-Channels, if utilized one ca have 16 byte access granularity.
GDDR5X also supports a Pseudo-32-Byte-Mode:

Then, release it when it's ready?
From said driver's INF file:

Note how 22.19.384.2 shows up in the posted GPU-z of VEGA FE screenshot as well.
Then they'd miss the H1 2017 release goal.
These kind of "Funny how..." posts never get old, do they?
Well... which is worse for AMD? Bad benchmarks or a month delay with (hopefully) good or at least better benchmarks?
I could be wrong, but I thought that the prefetch length increases from 2n to 4n in pseudo channel mode for HBM2. So it's still 32 bytes.
Pascal was already proven at that point. Who knows what's the state of Vega exactly is. A press briefing would have done wonders for damage control.

As written above, that would mean failing the H1 2017 release window which could mean significant repercussions from investors.
That's the thing: this is the month delay.
From the wording used at anandtech's articles I'm 99% sure the whole press had been briefed that all the gaming cards would release at Computex, and everyone got blindsided with that short and vague Prey demo.
As ToTTenTranz said, this is effectively a delay and the FE seems to be made specifically for appeasing the shareholders. AMD seems to believe this is the better course of action.
Those are forward looking statements. Schedule slips are a fact of life. Unless AMD provably misled investors, there'd be no repercussions at all.
You are right, I didn't looked at the prefetch lenght.
It increases from 2 to 4 so effectively it stays at 32 bytes.
So apparently there's the "dual pro/game-drivers" and separate "game drivers" now? https://disqus.com/by/klaudiuszkaczmarzyk/
