Since a fellow Android personality is dropping insider Nexus rumors, but doing them slowly, let's see if we can help by speeding up the process a tad. :)
Here is what we have heard (though the news is at least a month old):
-Last date we were told that Google had penciled in for a Nexus 5, Kit Kat, other Nexus unveiling was October 31. Google rarely hits their dates, so don't get too tied to that date.
-The codename for the Google-made watch is "Gem," first mentioned here: http://www.droid-life.com/2013/09/25/bigger-deal-new-nexus-phone-android-4-4-google-watch-or-something-else/
-There are two other potential Nexus devices in the works under the codenames "Sauron" and "Molly" that could arrive with the Nexus 5 and Kit Kat. I have no idea what they are. Could be a new Nexus 10 or something we haven't even thought of.
-Last, is Google working on Android@Home stuff finally? We have heard of two other potential "Nexus" type devices called "Leep" and "Shining" with TBD arrivals.
That is all. Rumors, just rumors. Things always change with Google and none of this could end up being official.
