According to Weekly Shonen Magazine and Weeky Shonen Sunday, Negima movie and Hayate no Gotoku! movie will be premiered in tandem on August 27th. The titles are "Mahou Sensei Negima! Anime Final" and "Hayate no Gotoku! Heaven is a Place on Earth". It's unusual that two competing publishers collaborate with each other on their anime movies.
The Negima manga is better than it's anime, however the Hayate anime is better than the manga imo. They're both very good titles and I'm glad to see them finally getting the attention they rightfully deserve.
It'll more likely be only in japan^^
Seems to me that only big otaku understand HnG. I guess normal (if I can say this) people usually prefer Negima cause it's more the shonen type. Ah I'll precise that I'm A big fan of the two (still like HnG a bit better).
I hope the HnG movie will be an original story. I like to discover new way of enjoying the same manga.
