I wonder if they are cheating a bit with Spiderman and Batman. I'm not sure they ever had just the Spiderman license versus a Marvel license. It looks like they show 15 Spiderman sets, but Marvel has more than that. Batman initially was a stand alone license, but has since been lumped in with DC.
As for Star Wars, that number looks accurate based on my spreadsheet of my collection based on the sets MSRP.
