No, I currently don't have any plans to add such support. But note that any developer can write their own tag support pretty quickly by using the WMP Tag Plus SDK.
Or, even better, support for DTS tagging could be added to the TagLib library. It seems that DTS internally stores tags in APEv2 format (which TagLib already supports). Once TagLib supports DTS, I could easily incorporate this into WMP Tag Plus since the plug-in already uses TagLib for other file formats.
