SuPa- planned to make some fantasy models. I also know someone recreated the Blademaster and Demon Hunter models nearly identically to the Warcraft III originals.
I'm afraid, though, that the quality of these models will not be the same as those that came with Starcraft II. We have a model that has many more polies, plus three textures, plus an animated portrait and a static one, and, of course, the animations, one of the tougher things to get done.
The models people made for Warcraft III were not always as polished as Blizzard's, including the fact that 99% have copied animations, and I'm afraid that that is a reality that's only getting aggravated in Starcraft II, given the increased complexity of the models.
