You mean Vulkan? They pretty much gave it away to OpenGL to continue on and will be using the current Mantle as their testing API for new features.

Vulkan is using parts of Mantle, just parts of its specs, I'm sure there will be differences once Vulkan is ready for use for developers vs what Mantle was.
OpenGL will not use Mantle for testing, AMD will use Mantle for testing new features that's quite a bit of difference in statements don't you think?
Once you have a fork in software development from a fundamental specs point, it is pretty much not advisable to go back to an older version and start making changes there, because that just undermines what is being done for advancement.

But now we know why. AMD's Robert Hallock confirmed on a blog post that Mantle had, for the most part, been turned into the Khronos Group’s Vulkan API that would supersede OpenGL.
“The cross-vendor Khronos Group has chosen the best and brightest parts of Mantle to serve as the foundation for 'Vulkan,' the exciting next version of the storied OpenGL API,” Hallock wrote. “Vulkan combines and extensively iterates on (Mantle’s) characteristics as one new and uniquely powerful graphics API. And as the product of an incredible collaboration between many industry hardware and software vendors, Vulkan paves the way for a renaissance in cross-platform and cross-vendor PC games with exceptional performance, image quality and features.”
There will be large differences from Mantle is what I take from this statement.
