For Kodak, RadioShack, and Commodore, the writing was on the wall for months or years before the bankruptcy. We haven't seen that here with Hyperion - and remember they just launched a new product which would have required cash on hand to manufacture.
Actually the writings have been on the wall for quite some time, it's just that some refused to look.
Hey one might even argue that this outcome was predictable form day one and only the massive delay is thze suprise....
As for Hyperion having just launched a product...... perfect time to go after outstanding debts (either directly or via a court).
