The new Dark Eldar look much better than the old ones. although there is no chance I can start a new 40k army, I'm definitely thinking about them for a kill-team!
The Chaos stuff from Warhammer Forge also look really good, the only problem is that I said after the current batch of Chaos stuff i'm working on I wouldn't get any more.
And last but not least, the Chaos Dwarf. At the minute they look just like extra warmachines for Chaos, but then there's this guy, who looks like a army general, so maybe we will some Chaos Dwarf infantry.
