I'm hoping to discover whether there is internal design improvements (connoted by the name "air lens") which make a real difference. I heard Paul's description in the video, but I'm not sure whether that technology is elsewhere, too, and whether it matters, much.
Until we can listen, yes, this is "speculation." But those who follow the developments of this arena of technology may have some good guesstimate as to whether there is some actual engineering in this thing which will prove game-changing.
