Crunchyroll and Funimation recently announced that their partnership, which shared the anime catalogs between the two streaming services, would be coming to an end on November 9. But fans have been wondering just how much it would have an impact on each of the services.

Providing an update to users on their forum, Crunchyroll revealed the 20 most popular anime series leaving the service on November 9, and stressed that the list is not complete or final as details are still subject to change. They just want to give fans a chance to enjoy the series before they're gone.
