Hey Monsuno Fans! Usually I've restricted myself to Japanese side of news, but this did show up on a Japanese Animation News website and it gave a more concrete release date for the North American release of Season 2, Monsuno: Combat Chaos.
Now, is it good news? Not exactly. While we did get a more accurate time frame what "Later in the year" means, you might not be happy what I'm about to report.
According to Anime! Anime! Biz, it was reported that new Episodes of Mosuno in the United States would not be hitting this half of the year, rather the second half of 2013. This would indicate that plans to release the series have now been delayed until the Fall or Winter season. If I am understanding the article correctly, it appears the tactic is to focus on increasing toy sales during the first half of the year, while also doing repeats of the first Season.
As to why the release has been delayed, nothing was specified. It is possible the 2nd Season has not been finished and Nickelodeon is waiting for the full production order to be finished before commiting to broadcast.
For reference, Studio Wanpack's website, which lists what shows/works they have done by Month and Year, indicated they had just completed work on Episode 33 (Season 2, Episode 7) in December. They had also finished up work on Episode 29 (Season 2, Episode 3) in October. Provided Larx Entertainment / Studio Hibari were only up to Episode 33 in December, at the current pacing, they probably have not completed work on the entire Season 2 run as of this posting.
I'm hoping that this changes so there won't be a long wait between Japan and the United States. I'll keep you guys up to date with available news on the Japanese front.
