I can tell you that they are definitely aware of the thread and interested in the responses. As for what they may or may not be considering or developing, I wouldn't expect to hear a peep until they unveiled it at one of the shows or posted on their web site. I've spent some time in product development and manufacturing (non-RC) and I know first-hand some of the secrecy involved.

The best thing we can do as customers is to continue sending the message. Developing something like this is no simple process. It takes a lot of time, people and ultimately money to get something from an idea to a finished product complete with packaging, marketing, etc. The manufacturer will usually make the investment if they are confident that the market exists and they can make a profit.
