Not giving anything away here, but there are rumblings about the need for automated cars and drones to operate in a fleet, connected to each other and part of a fleet control center. I'm aware of at least one company making an announcement about a drone fleet. (Amazon has already started delivering products by drone in the UK.)
3. Augmented reality that actually helps you
Augmented reality (AR) was more like a magic trick in the past. At CES 2017, I'm expecting to see AR that provides actual help in some way. AR is like an overlay on top of the real world. Microsoft HoloLens is a leader here, and I'm expecting to go hands-on. One example from 2016 of how this works is the Lenovo Phab 2 phone and the Lowe's app. You can use it to measure the space in a room and find out if a couch will fit.
7. 5G debuts
I already have a few meetings to test out 5G service, the next wave of cellular connectivity. I remember testing 4G at CES for the first time a few years ago. 5G promises consistent connections with more access points not just a speed boost.
