Google just posted the factory images and drivers (binaries) for Android 4.4 KitKat, build number KRT16M. While they wont do most of us much good — as we don’t yet have a Nexus 5 in our possession — it’s nice that they’re already made available should anyone need to return their Nexus 5 back to its original factory state. You know, once you actually get it. We’re gonna dive in and see what we can extract but in the meantime, download links provided below.

Is it possible for devs to take the source code and make it on a macroscale for the Nexus 7 2013 model?
It seems like most devs use stuff from Mako for Flo since the hardware is essentially the same except for the screen size. The N5 will have entirely different hardware, so I don’t think they’d do that.

And the other devices get shafted, get used to it folks, users of previous handsets are going to be second-class users from now on.
