So, we're just going to stay with 8th edition, right?
I kid, I kid. Still reserving final judgement until the rules come out. Chaos stuff looks good, and the one thing I will say about the Sigmar stuff, even though nothing about them screams "Warhammer Fantasy" to me, is that it definitely screams "Games Workshop," although maybe a little "Privateer Press" too. Certainly going to be a lot harder to find alternative miniatures to use with your "not-space-marines gold lightning angel knights" army, so in that respect GW has succeeded. Still, as a guy who is looking at playing Empire (...Sigmarites?), this has got be a bit worried. But again, will wait for the rules to come out before I make any final decisions.
If nothing else, you guys are more than welcome to come bring your old square bases and push them around Mordheim with me, heh.
