In a very unsurprising move, new slides out of SIGGRAPH 2015 from Valve talk about Source 2 and Vulkan. The game featured is of course Dota 2 Reborn. Since it's Valve's most popular game, and their first game to use Source 2 it was to be expected.
It will probably be the first game on Linux to use Vulkan, so it will be very, very interesting to see how it performs against the OpenGL version. I really hope Valve have a setting we can change easily to switch between the two, as it will make comparisons easier, and not all drivers will support Vulkan at the same time.
I haven't been able to find the video that goes along with it, as it seems it's still sadly being hidden.
You can find the slides here if interested in developer stuff. Article taken from GamingOnLinux.com.

Great news, though indeed nought too surprising.
I expect them to include a -vulkan launch option, at least till they prioritize it after the drivers stabilize, just like they do for direct3d versions in windows.

Dota is love. DOTA is life.
(Lol I just launched DOTA and the loading screen gets 2099 FPS)

I'm not game dev but those slides look rubbish to me without the actual talk. Let's hope one is posted soon although I fear it will be too technical.

The NVIDIA talk about Vulkan is quite interesting too and there is already a video : View video on youtube.com

we got to have Vulkan drivers then though, and if the GoL Survey is any indication people want those in their bin-blob drivers.

I'm sure AMD will (try to) do the same. There's already a preview implementation for some Intel GPU models with Vulkan, done by LunarG. Again, this will apparently be released as open source as soon as the spec is final. Hopefully other OSS drivers won't be far behind, as Vulkan drivers seem quite a bit simpler than their OpenGL counterparts.
EDIT: The intel driver isn't actually released as open source yet.

Any ideas when they might release this or when the spec is expected to be finalised ?

Any ideas when they might release this or when the spec is expected to be finalised ?"Later this year" or "by the end of the year" according to various presentations at siggraph.

Not related to Vulkan directly but, there is an interesting comparison for dx11 vs dx 12 (the same idea as Vulkan) on arstechnica (AMD vs NVIDIA):
http://arstechnica.com/gaming/2015/08/directx-12-tested-an-early-win-for-amd-and-disappointment-for-nvidia/
In short AMD almost double the performance NVIDIA lowers.

Still kinda sad that it's dota 2... not exactly a showcase kind of game. Maybe we'll get portal 3 or somethin to make up for it.
Personally, I agree with you since I don't like MOBAs, but from Valve's perspective, the game has millions of players (sometimes over a million logged in at one time). PC gamers are crazy about their MOBAs. I just read an article about a kid who won their championship [now being a millionaire](http://www.gamespot.com/articles/meet-the-16-year-old-professional-dota-2-player-wh/1100-6429598/). So, yes, it's a showcase kind of game and makes Valve a lot of money.

Wonder if they'll be able to be ready by November. Also I'm curious whether the two new APIs will remove the need for Crossfire/SLI profiles - a huge problem in Linux. At the moment anybody with more than one GPU basically has an expensive dust collector in their case.

At the moment anybody with more than one GPU basically has an expensive dust collector in their case.As far as I understand, Vulkan allows developers to spread the workload between any Vulkan-compatible GPUs in the system as they see fit. No need for special SLI/Crossfire kludges and no restriction to single-vendor hardware combinations. It remains to be seen how this works out in practice. No Idea about DX12.

That's impressive for AMD, and shows that Nvidia isn't exactly going all out on supporting DX12 yet. But we haven't seen vulkan stats, the scores might be closer on that scene.
But then again, even on DX11, Nvidias cards are outperforming AMD on DX12 on that benchmark in the end.
It might very well be that the nvidia card are winning in the end, but keep in mind that the nvidia card was released this summer and the amd card was released late 2013.
I think it's quite interesting to see a nearly two year old card from amd almost matching a top notch 980Ti. I would have liked to see the benchmark with a Fury X vs the 980Ti though...
If Vulkan bears resemblance to DX12, I can imagine how amd cards may improve in Linux when using the Vulkan API.

Everyone knows that AMD's inferior OpenGL driver has held them back on Linux. By how much, we'll see. Let's not jump to too many conclusions based on a single benchmark.
