When do you anticipate that a DirectX version of HarBal will be available? I do all my mastering work in Sound Forge 6, and it would be a lot more convenient if a plug-in was available.

We have no plans for a plugin. You can’t do what we want to do with Har-Bal as a plugin. The interfaces are too primitive in what they give you access to. It is important to note that it is difficult to “efficiently” support the mode of operation required for Har-Bal as a plugin, simply because the plugin interface does not give enough control/access to the source material as Har-Bal would require. It is possible to do something similar but the means of operating the software would be decidedly clunkier than the standalone version.
