I think the concerns/doubts/questions being raised are all fair and are the very reason that, if what the company says they have done is true, will make the share a game changer for the world of sound. If they are lying then they have obviously managed to convince some smart people at Sony that the tech has the potential to be big... Which makes it some lie.
obvioualy we might find that they just can't take it all the way to market as it's not possible to make it do what they want at the price they need... Despite all the promising progress so far. That's a real possibility... But that's also why the company was only valued at $175m a couple of weeks ago and why it's only $350m odd today when success makes it worth billions. Most are still betting it won't succeed.
