We've updated the product listing excel sheet on our website to bring it current. As for creating a new catalog section for retired items, I'll think it over. It is a nice tool for collectors, I agree, but I'm not sure the effort in time is worth it from our perspective to maintain catalogs for items we no longer sell. The product listing is meant to take care of that for us as it lists all sets including the retired ones. Of course, we should update it with every new release and will do so moving forward.
Best,
Matt
