I just got a email back from UA:

Hi Eddie,

We do not have a release date as of yet, however, we have recently acquired an amount of DirectX software for development, and have firmly established that DirectX support is in the pipeline.
Keep an eye on our website for update information and news: http://www.uaudio.com/PPI
