I've been messing around with a RealSense depth cam lately and it's been somewhat interesting. In the past I played around with an old gen1 Kinect using stuff like TouchDesigner and ZVector but had to hold off on picking up a gen2 Kinect when the adapter needed for PC hookup was somewhat pricey and always on back order.

I haven't gotten into the gritty details yet and have only been using it with TouchDesigner and ZVector Touch so far but it's fairly promising as a low cost, decent quality RGB+depth camera.

I presume these assets were bought so they would have a competitor to Google's Project Tango if it takes off.

The first Tango phone from LG is far too big and underpowered but future Android phones could have this stuff built in unobtrusively. Couple that with better AR games (a new version of Pokemon GO, for instance) and Apple will badly need something similar to compete.

Oh yes, that's a good point. I really hope they release something based on that.
