Here is a post from the UA forums on the DX plugins:

We'll be showing DX versions of the UAD plugins at NAMM. These will have full delay
compensation within Sonar and other DX hosts. We hope to include these in our 3.0 release,
but we'll know for sure by the show. In the mean time, the latest version of the FXpansion
wrapper has been tested with Sonar and works very well with the UAD-1.

Plus if multicard support is included I'll be stressed to get a second in the near future. This is going to be a interesting newyear!
