Don't forget DAT. You're right, Sony does seem to specialize in failed formats. Not bad formats technically, but they don't know how to support it. I've read where they do it on purpose. They would rather have the pond to themselves and have it dry up, then share it. They figure their R&D can always find another pond. They may be correct, from a business standpoint, if not from the customers standpoint. They are pretty much a monopoly. Nobody dominates the hardware AND software ends of the market like Sony.
I don't think they're writing off huge losses. By owning the whole pond, they're cleaning up. Have no pity on Sony, only their consumers.
