Next Version Of Android Likely To Be 4.3, Not 5.0
Even though I/O is Google’s biggest event of the year, it is not the event where Google announces the next major version of Android.
Gadgetronica has said that Google has delayed 5.0 internally due to OEM issues, which means it will not be ‘ready’ for I/O. My understanding, which matches up with Google’s past behaviour, is that 5.0 was never on track for a release at I/O.
