Staggering the amount of mini's they are going to have to produce for this though if we're just talking Vampire Pledge with no extras and ignoring everyone else who gets mini's both below and above. as of right now that's 217 x 10,037 = 21,708,029. And that's just the base for Vampire level pledges.
I think you added in an extra digit there, just calculated myself based on some recent numbers:
223 figures x 12040 Vampire levels = 2,684,920 miniatures Reaper needs to make to support the Vampire pledges alone. Not to count the tons and tons of options everyone is going after, the other reward levels, or if people are opting Sophie out for multiple figures.
Which is a bit higher than their current pledge level of $2,492,795.
So, I can see why the stretch goals have been creeping up and up and up.
