Pricing has to be seriously tough for GW to work out if you think about it. Probably 80% of a models sales will happen during it's initial release window so they have to make a good estimate of how many they think they can sale vs the cost vs what they need the kit to provide in profit. Too high risks people not buying the kit and too low risks not making the amount of profit they targeted. Not a fun job for them to work it out at all.
