We know the Google mobile-first index isn't launching any time soon and there were rumors it won't go out in 2017 because hitting quality neutral has been a harder thing to achieve than they once thought.
Gary Illyes from Google said in the mobile-first panel at SMX Advanced yesterday that it is now likely not going to launch until 2018. Gary said we are "many quarters" away from a launch. In fact, John Mueller recently said they might even launch it in batches. I even asked and pushed for a sandbox preview but was denied again.
Matt McGee at Search Engine Land has an excellent write up on it.
Here are some tweets from the attendees:

Do not freak out about the mobile first index. We don't have a timeline for the launch yet. It's probably many quarters away@methode #smx

Mobile first is going to be a BIG change. But @methode says "Don't freak out." There is no timeline for launch. Many quarters away. #SMX
