According to some recent "in the wild" intel, it appears that Google may already be in the testing phases of Android 5.0/Key Lime Pie. The new generation of Android with the "K Series" build number specifically KRS36B was spotted running on a Nexus 7 and a Nexus 4. This new build of Android was spotted at the Chromium Project in a brand new bug report.
If Google is already in testing, then the rumored Fall launch of the new OS from Google could turn out to be accurate. Who is craving dessert now?
