Crann Tara Miniatures have just announced that they will be releasing the Monolith Graven Images range. For those that don't know about these figures, they are 40mm, so they will not fit in with your 28mm games. The figures have a very different style to them, but are simply amazing IMO.
Here are some cool examples of figures that were sculpted. I am not sure if all these will be available or not.
To see more images go check out Jim Bowen's Graven Images. There is also a Yahoo Group that has quite a few images.
