Google's Android Twitter account just sent out the above Tweet this morning. As you can see, Android 5.0 Lollipop is now rolling out to most Nexus devices. While the specifics aren't mentioned, you get bet they are probably referring to Nexus 4, 5, 7, & 10 devices.

Nexus owners can now start feverishly clicking "check update" obsessively...

Thanks for the tip, [USER=19076]@Garemlin[/USER]
