From they Dynon forum from Dynon Support:
"Thanks for your patience on this. Delays getting the initial autopilot release out the door have backed up our schedule a bit. As a result, we've had to make some hard decisions in order to get the next generation out in a reasonable timeframe.
With software development winding down on current generation we've decided that the majority of our resources for the forseeable future needs to be heavily concentrated on the next generation product line. We will still be releasing firmware version 5.1 for the current product line which adds several improvements to the Autopilot. However, AP76 development is on hold for the foreseeable future.
As far as future autopilot development is concerned, our current plan is to to bring the next generation products to the level of capability that exists in our current autopilot. When we reach that milestone and move forward with more advanced autopilot features, we will re-evaluate our product mix and determine whether it makes sense to restart AP76 development, or whether we should offer those features exclusively on the next generation product line. Realistically, this means that the AP76 will not reach the market before the end of 2009.
In the meantime, we WILL continue to add additional airplane support through Dynon-produced mounting kits and the release of capstan servos (for cable-drive aircraft). We will also continue to support and troubleshoot the Autopilot and all other current products at the level our customers have come to expect."
One word

I have not ordered my avionics/ap yet so my loss to this point is in the hours spent laying out and cutting a panel based on this solution. Those of you that have already bought in have more to loose.
Dynon, this is not cool, not cool at all!
Your own website is still continuing to promise the AP76 and its advanced features...THAT WORK WITH THE CURRENT PRODUCTS!
