The QA department at TEAC has to do their full set of tests on OS X 10.9, which just went to GM. I expect that this version (V1.30f4) will be our final candidate, but can't guarantee it.
I've already done some tests, and noted that I forgot to add a developer signature to the uninstaller, but apart from that it works fine. We don't have access to every Mac that Apple makes, and frequently they make changes in hardware that affects driver compatibility, so if you're first in line for the new Mac Pro, we won't know how it's going to behave in advance...
