Except the little detail that there is zero Vulkan support on:
- iOS
- macOS
- PSP, PS3, PS4
- Wii U, 3DS
- XBox 360, ONE
- any Android version < Android 7
- UWP

But the point he was making was that there is no need for DX12 because Vulkan works everywhere else.
Right now Vulkan is only supported on custom Android 6 forks for Samsung S7 and NVidia Shield, Android 7, GNU/Linux and Windows on a restricted set of graphic cards.
Hardly a market to target for game developers that want to reach as much eyes as possible.
Just think how much more popular Windows 7 is compared to DX12. Xbox One is nothing in comparison.
Windows 10 users are already 45%, with around 41% having DX 12 GPUs + plus around 20 million Xbox One units.
As for market size of Vulkan, some S7 and NVidia shield as part of 10% Android 6, 0% on Android 7 until it reaches stable and of course those other 55% users that might have a Vulkan compatible card.
Because all three are APIs which try to provide a lot more control over the GPU to game developers. And I wouldn't know of any other similarities that DX12 and Metal share...
I very much doubt Microsoft will bother to support Vulkan if AAA studios don't ask for it.
They will eventually, when they'll get fed up with MS lock-in stupidity. In order for it to happen, competing market should put more pressure on MS. MS drops lock-in only from fear of competition. And it will eventually happen - there is no need for reinventing the wheel.
People call that MS tax, since it makes their development more costly. Whether it's developers who work on their own engines, or engine developers who provide their engines for others, this cost is passed to the end user in the form of more bugs, slower development and so on. No sane developer appreciates lock-in. But currently they have no choice.
I really bet none of those ever walked the floors of GDC.
Anyone who thinks and cares about progress and doesn't drink Koolaid served by MS and Co. Surely not lock-in freaks, who frame their tax on the industry as something positive.
> I really bet none of those ever walked the floors of GDC.
You sound like GDC is owned by MS, or it's ought to be. Are you paid by them? Either way, it's a very poor way to measure opinions or their value. Find something better.
No one in GDC hallways speak of lock-in as activists believe they do.
There were many talks on GDC about Vulkan which discussed lock-in issues that it can solve.
And surely you don't expect MS and its cahoots to talk about lock-in. They are pushing it to mess up everyone else, so they aren't going to bring this crooked practice into the spotlight.
Anyway, here are people whose opinion is interesting, regardless of GDC:
