The problem is that the reporter, wasn't actually seeing anything. There was no 3d model constructed in real space, on thin air, in the studio. They simply took a video on a blue/green screen background, and then merged it with the studio video in real time. A "3d video" in a sense, so they were able to match perspectives with the studio camera movements, buts its probably not what you think.
Unfortunately the whole point and difficulty with the sci-fi idea of "holograms" is that it requires the ability to have light stop and turn mid airs. Which is a bit trickier than it sounds.
The closest and most impressive I have seen is the Heliodisplay (which actually projects on a really really fine mist of water vapor), which, if combined with a camera, would in fact give you
exactly the Star Wars effect, although the image is flat.
