@sfoLAX was that some kind of "this page intentionally left blank" moment? lol
To answer the question as asked - some of us have it already To qualify that answer - this REALLY depends on what device you're asking about.
Will a Samsung S4 get it? Nope
Will a Nexus 6P get it? It should already have it.
Will a Samsung S5 get it? I'm actually not sure but it's unlikely.
