I too hope for a revitalized Tile Editor. Tile building was loads of fun; it was almost like its own game. And all of my tiles used pedestrians. They really helped liven up a scene.
[tangent] Of course, the big problem with the T.E. was that it didn't tie in to the rest of the game (short of XML modding). Tiles were cool, but there was nothing you could do with them, in-game, after they were created (again, short of XML). I hope that, in Fallen Enchantress, we get to see the fabled quest editor, and maybe then it'll allow the Tile Editor to really take off as a fantastic tool. If so, then I'd love for pedestrians to come back, complete with loads more animation options. [/tangent]
