So was the amount of models in "Assault on Black Reach"...
People still buy those? I imagine Necron Pariahs sell better.
And? If we don't do the Chaos sets, those players will moan. This is a GW hobby. People always moan. Always. About everything. My favourite this year was one person complaining that GK's were going to be dull because they'd just be "another version of marines" then complaining that GKs were "completely different to regular marines!". I kid you not, the sense of entitlement GW fans have is second to none. Except, perhaps, computer game fans.
But less awesome. So nowhere near as good.
Also, consider "Space Hulk" 21 completeley individual character Terminators. My numbers are definitely aiming for the stars, but considering Titanicus 1st ed actually did come with six Warlords, I don't think I'm being that unrealistic... Well, about the Warhounds, maybe.
