It's been known for a while now, but finally we have confirmation of the Negima movie. It's double billing with a Hayate The Combat Butler movie and is titled "Anime Final"...which means sadly that it's probably the last animated Negima we will ever see. (Still, given how "Final" doesn't always mean "Final" in some cases...)
Presumably it's covering a good chunk of the current manga arc after Another World's OADs, but there may be parts cut for time. It may be way too early but I am hoping this is in Funimation's sights.
