All our data for Dynamite future releases come from Diamond solicitations. The variants they provided to Diamond also isn't always organized in a way the cover gallery might state inside the printed issue. Another problem is that they don't get all the variant cover info for a given issue like store variants, convention variants, etc. We typically learn of a issue's complete cover gallery on its release day when we have a physical copy to reference and/or a user sends us a correction for a variant we don't know about.
