The Kinect has a very limited range, is not accurate and works only in certain lightning condition. That's why they added a laser scanner. Those are over $1000.
Then in order to build the map via SLAM in real time you need a really powerfull PC/Laptop. Even a netbook is not going to do it, at least for the SLAM in ROS(ros.org).
Then it looks like they added a all angles are 90° assumtion, because normally the map does not look that nice because little errors accumulate.
So it will take a while till we see something like that outside universities.
Kinect-like sensors are going to improve very quickly (http://www.theverge.com/2012/2/29/2834088/samsung-camera-sen...), as are SLAM algorithms using Kinect-like data. High cost isn't necessarily a problem for this application, as one team of copters could map many facilities. Computing power can be mostly centralized at a base station that can be as beefy as you want. Certainly a commercial product is years rather than months away, but I think even this limited demo could already be useful for e.g. mapping the nuclear reactors at Fukushima.
Hey quit being a letdown, this really amazing stuff. You should reword it more like:
"The video is showing amazing new thingamabobs that will get less expensive over the next few years, and pretty soon you will all be able to use robots like this in your everyday life".
