Ok then Inaba why dont you buy 7k of the boards off them then? The problem is the money they got from the preorders went to finance the development of the product. If they cannot develop everyone just loses their money. Why not produce something that can make the numbers they claim? Well thats simple they obviously just cant. By showing any product they make it look like they are more legit.
Given that they seem to have told many untruths I have a hard time accepting any of their claims now. Yes there are legitimate companies that scam and you can buy stuff from illigitimate companies but that is another red herring. When you are hiring several staff members as they claim to be you wouldnt be running out of your house still. To me the simplest explanation is that they just cant deliver on their claims. They seem very dishonest overall.
