Thanks for posting that picture, fluffystuff! I was only aware of the first 5 heroes previewed, and of the kobolds (hadn't seen ogres or dragons yet - cool stuff!).
All that at a pretty reasonable price point pushes this from a "would be fun" to "definitely (if I can scrounge up the cash)" game.
From that picture, it looks like the minis will be cast in plastic, right? That was another deterent for me - they're cool figures but they look like a pain to assemble and perhaps too easily breakable in metal.
