A second movie for Inazuma Eleven has been announced to start showing in theatres in Japan on December 23, 2011 (same date as the first movie a year earlier).
Japanese title: 劇場版 イナズマイレブン GO 究極の絆 グリフォン
Romaji: Gekijouban Inazuma Eleven GO Kyuukyoku no Kizuna Gryphon
English: Inazuma Eleven GO the Movie The Ultimate Bonds, Gryphon
Inazuma Eleven GO for 3DS is scheduled for release Winter 2011 (Q4).
The source also has information on upcoming GO anime stuff, but I won’t go into that for now. More details later possibly.
As a side note, LEVEL-5 and Gundam were in this magazine too.
