There is the Asus Xtion which is a knock off Primesense Carmine. Google Tango is basically the same technology, as is Apple's Face ID*. Intel's realsense systems are also similar, but I don't know anyone who actually uses them.
Unfortunately Microsoft missed the chance to buy Primsesense before Apple snapped them up. Still, while the tech is good, the ToF sensor in the Kinect v2 is superior for the (gaming) market and Microsoft own the IP via their Canesta acquisition (they licensed the Kinect patent).
What's more interesting is the boatload of cheap ToF systems that you can now buy. The only problem is they're much more power hungry. The new Kinect is crappy for mobile robotics because its heavy (90% of the sensor head is heatsink) and needs a wall power supply. It's fine for static systems, or beefier mechanics though.
(Face ID is literally a mini-Kinect, since it comes out of Primsense IP.)
