The last page of volume 99 of Hayate no Gotoku (aka Hayate the Combat Butler) announces that a new Hayate anime production has been green-lit. However, it does not mention if it will be an OVA or TV or another movie. Volume 99 of Hayate no Gotoku or Volume 0 of Mahou Sensei Negima was distributed to movie goers of the Hayate no Gotoku: Heaven is a Place on Earth and Mahou Sensei Negima: Anime Final double billing which opened today in Japan. Here is a picture from an audience member:
So far the franchise has had a 52 episode TV series Hayate no Gotoku! animated by SynergySP, a 25 episode second TV series Hayate no Gotoku!! animated by JCStaff, and the movie animated by Manglobe.
