I am receiving information now on the DDA-120 ($699 suggested retail)
It will be similar to the DDA-100, but will have the following:
1) L&R analog inputs
2) Bluetooth input
3) Async USB
4) Suggested better sound quality
I have not been informed as to if it is a replacement to the DDA-100, or an addition to the line.
I will post as more info is available
