Blizzard have spoken up on the reuse and re-colouring of models for their latest patch, Fury of the Sunwell (Patch 2.4), and also mentioned that all designers are working on Wrath of the Lich king. The new graphics in the expansion will also be "far and beyond" any previous visual experiences.
This becomes extremely interesting in the light of the Burning Crusade model upgrades, even if they were relatively small, and the reworking of ALL character models (even if it was only noticeable on the Human females)...
