Images of the new Dwarves are now floating around the internet virtually everywhere. There are lots of them, and I have to say these models are nice. Games Workshop has proven themselves with these, so check them out.
There are quite a few pics out, and lets start off with the 40k Warzone, and then you can leap on over to Bugman's Brewery to check out even more. These are really spectacular models, and pre-orders go live here in a few days now.
