For example: if I wanted to convert my game from DirectX 12 to Metal or Vulkan, the process would be "easier" than porting between OpenGL to any of the new APIs, correct?

Certainly should be.

I don’t know of any other resources than what you have posted.

Vulkan is currently on track to be released before year's end. They're still wrapping up some bits, since they're not worrying about rushing it to meet Windows 10's release date (like the DirectX team unfortunately had to).

Yes, D3D12 and Vulkan are very similar. Not identical, but similar; the core hardware concepts are, well, hardware concepts, so they're the same in all the new APIs. And yes, that means it'll be easier to port from D3D12 to Vulkan than it will be to port from GL to Vulkan.

So far as D3D12 learning resources, Microsoft's documentation is fairly decent, and they have official sample codes on GitHub. And you can use the existing D3D11-on-12 support to gradually port an existing codebase.

More documention will be on its way. There's some more in-depth samples, videos, and documentation that Direct3D insiders had that haven't been released publicly yet (that I know of) for some reason. Plus all the skilled tutorial writers (who, sadly, are not generally the kinds of people that had insider access to either API) haven't had any time yet to write D3D12 tutorials given that they just got their mitts on it, too.

Expect Vulkan's release to be similar: some documentation and tools up front, but most of the good docs and tutorials and whatnot won't likely emerge until months after release.
