>>6257464That chart is just toy sales for each quarter rearranged by show. I'm speaking from experience for W and OOO both from online shopping and actually being in Japan when they were airing when it comes to trying to find toys.
If you actually list the number of toys shows have planned in the catalog, W certainly has fewer than the shows that come after it.
Bandai has also made statements about certain toys. The Sengoku Driver sold 700k units by the June of Gaim. The OOO Driver sold 750k and the Fourze Driver sold 800k by the winters after their shows ended. There were like 33 million Astro Switches sold.
