NeXTBSD, aka FreeBSD-X
FreeBSD hackers Jordan Hubbard and Kip Macy surprised an audience of Bay Area FreeBSD Users in August 2015 by laying out their version for a new architecture, based vaguely on BSD but with a microkernel and an event-driven framework consisting of something like libdispatch and launchd. Those are big changes if you are familiar with what FreeBSD has looked like for all of its life.
The good news is, this doesn't mean the destruction of the FreeBSD we all know and love. In fact, Hubbard, who is also the CTO of iXsystems (developers of FreeNAS and PC-BSD, both products derived from FreeBSD) aren't aiming to impact FreeBSD but rather change the fundamental architecture of iXsystems' own products.
The slide deck walks you through the proposed, new architecture. Better still, watch the talk yourself, before heading herefor some useful comments to help sort it all out. Others are watching this project with suspicion, too. Check out this excellent rebuttal on the DarknEdgy blog, which suggests, among other criticisms, that the Mach microkernel is an anachronism.
As a FreeBSD fan, I'm glad they're treating this as a separate product and not hacking up the FreeBSD source tree: that gives us time to see how this shakes out.

I'm not shocked.
