One thing I've always been curious about in gaming is in the codes every company gives their product. In Wyrd's 2010 catalog (Which I have now, woo!) there are gaps in the listings for each faction. For example, the Guild has no entry for WYR1013, and the Resurrectionists don't have a WYR2019.
Why is that? I know just about every company does this, particularly with minis, so I'm curious why it happens. Are those reserved for future releases, planned models that got scrapped, or something else?
