Clearly, they are working on something, because at least one forum member has been sent a copy of the new firmware. As for why they aren't talking about it, I think that can be traced to two things: their policy of minimal forum presence (after almost seven years, Scott has less than 500 posts, and Peter waited at least five years before even registering an account), and a policy of being tight-lipped about product updates in general as a sort of residual scar tissue from the Model 950 development (when they were a bit too open about projected delivery dates and got roasted on a spit in numerous online forums when the product ran into numerous delays).
