What is somewhat disappointing is that they don't tell if they have managed to solve these issues or not, as they were clearly commented on one year ago. Another major issue is the RAM-usage, as point cloud data will require a lot of memory.
Their claims of being 100,000 times better than current technology is also "frustrating", as it is repeatedly mentioned as if you've for some strange reason forgot it in the last 30 seconds. It is also a lie if they cannot use this in a game: I would suspect it's not impossible to increase the level of polygons to 10-100 times the amount - if not even more - if there's no animations or dynamic light sources around.
