With the Discords that are able to access and display meta data - we are able to see preorder limits on specific items. I thought it would be interesting to compile these and make some inferences about likely print runs.
I don’t think this data can be used to tell us the exact print runs of a PC ETB, but it likely does give us information about the sets relative to each other.
