We knew it was coming. Google was a partner of Vulkan since it launched, but support was coming at some point after the desktop launch. We expected that it would be soon, but now we know that the new graphics API is in Android N Developer Preview 2. Other platforms, like apparently the Samsung Galaxy S7, are able to ship Vulkan drivers, but it is “a part of the platform” in this Android N pre-release.
Vulkan is particularly useful for mobile because those devices tend to have many cores, but relatively slow cores, which drive a decently fast GPU. Whether the benefits end up being higher performance or just better battery life (as the CPU can downclock more and more often) depends on the application, but it can be useful for 3D applications, and eventually even 2D ones, like future Qt applications with many elements, or even web browsers (when drawing complex sites).
It's good that Google is supporting Vulkan, especially after their ban of OpenCL drivers from Nexus devices. We want a single GPU compute interface across as many platforms as possible. While Vulkan isn't as complete as OpenCL, lacking some features such as unified memory, it should be more useful than OpenGL ES compute shaders.

With basically zero warning, Google has released Android N previews for the Nexus 5X, the Nexus 6, the Nexus 6P, the Nexus 9, the Nexus Player, and the Pixel C. It can be installed by flashing the OS onto the device, or by joining the Android Beta Program. Personally, I'd recommend joining the program, because then updates are pushed over-the-air. Be sure to back up your personal data, too. Almost every method of installing or removing the preview build will intentionally wipe the device. (Technically, installing from the Android Beta Program shouldn't erase user data, but errors can occur, and, even then, the device will be wiped when you leave.)
Aligning with this announcement is a discount on the Pixel C. It is only available to developers, and only within the US. Also, before I found out that Canadians were not eligible, I tried getting a code and the website seems to silently fail. It basically just refreshes and no email is sent, so Google might have pulled the plug once non-developers heard the news. Android Police believes that it only applies to the 64GB version, but Google's announcement wasn't clear on that. This would make the Pixel C available for $450 USD, which is quite cheap for a 10-inch, Tegra X1 device.
Android N will have a few user experience (UX) changes. The two most obvious ones are app splitscreen, which behaves like Windows 8's Windows Store app snapping, and “direct reply notifications,” which allows, for instance, replying to a chat message from the notification itself. Google has also moved to OpenJDK, as we mentioned during the holidays. This is an Oracle-approved, open-source implementation of Java that can be freely used.
