Hmmmmm, This has been brought up that it was a joke that Plastic Sisters are coming in a few months. Yes, that is what was said, a couple months. So would Games Workshop even say this if it was not really coming?
I can't say for certain, but I think it would be in bad taste if it was a joke. Squats or some other far out vague race would of been better if it was a joke. for now though, what do you think?
Personally the whole thing was made in fun. I don't take the Magnus model as a joke, so I wouldn't think the Sisters would be either.
