The problem with those models (and I suspect the same of the new WoD models) seems to be that there are too many geosets for the client to handle. You can remove geosets using a hex editor (which is what I did). I was able to get 1 female pandaren model to work (the pandaren prisoner) but all the rest had missing body parts. Some geosets seems to be important for some models, and not so important for other models.Will the WoD models be portable? Most likely, yes - with the right skill set. Perhaps between now and then someone will share their strategy for converting these models.
