Lets predict the state of Android in 5 years

My prediction - nothing will really change.

- another 1-2 major revisions of Android, using ART as the runtime

- new Nexus and new flagships like S5/6/7 each year

- oem skins will still be on most phones, and will still be far behind native experience

- the sad state of Android updates will continue.

- GPS (Google play services) will keep getting bigger and AOSP will be limited to the basic runtime and services

- custom rom's will keep getting harder to install as new devices won't have easy exploits

- widespread adoption of VoLTE *may* make all carriers ship unlocked phones which are truly interchangeable, but this is very very unlikely in the US.
