We fully expect the Nexus 5 along with Android 4.4 Kit Kat to be released next month, and if you need further confirmation, then take a look at the German Facebook page for Kit Kat. They posted the above image and the 11th comment (from Kit Kat) says, “Hi Tim, Android 4.4 KIT KAT ist ab Oktober verfügbar.” If you don’t know German, no problem, a quick Google translation yields, “Hi Tim, Android 4.4 KIT KAT is available from October.”
Of course I don’t know if I would really classify this as an “out” since Google doesn’t usually put statues on their lawn for a new version of Android unless they plan to release it soon. The statue went up on September 3 and they announced the Nexus 4 and Android 4.2 Jelly Bean last October. Thank you for the confirmation Nestle, but we didn’t need it.
