Android 4.3 has only just been released, a lot of high end phones dont even have the trim enabled bean yet, but google has already made a turn in the release setup of android.
So it seems today (as far as I have personally found) Google has decided to not pursue Android 5.0 Keylime Pie and follow a different path, Welcome Android 4.4 Kitkat.
Personally I prefer this move from the Android 5.0 update, 4.3 Jelly Bean is far from finished yet, I have noticed a battery decrease on my Nexus 7 since the update and cant fix it with a custom kernel.
So a minor update over a major upgrade maybe better as half of the locked devices have not got their 4.3 update yet. I have only just seen the Nexus 4 get update over here with locked devices.
So yeah, Google doing another sudden turn in the android lineup, impressive and I thank Google that they dont just ditch the 4 series yet.
I shall also leave you with this, a nice little parody video from Google which most likely seems aimed at the new series of Apple adverts with their whole 'Designed in California' style. And i have to say made me giggle on the inside.
