Most "OS" releases these days are not operating systems. They're new user space layers on top of Linux. Actually OS development doesn't happen much, and the word has been repurposed.
Even that is overstating it. They're just slightly different arrangements of the same set of user space components layered on top of the Linux kernel.
I think there's a lot of potential for actually completely replacing the user space layer on top of Linux, but no one has done that except Google with Android.
