I hope the H&A news is not an April Fool!
In the 'Yossie Fan Club Show' thread on 2ch all I found was this response to the question "ハンアンについて何か話しあったの?" (Was anything about Hangry & Angry talked about?)
「今年はドリ娘があって『ふんふふーん ふんふふー』もあるし」
って言った
「ハンプティーダンプティーじゃないよ」ともw
Which I'm unclear of the translation but I took it to mean
"There's Dream Morning Musume this year."
"It's not humpty dumpty."
Which I took to mean she has commitments with Dream MM this year but H&A isn't dead yet.
So if someone can translate that a bit better or has another source that'd be cool.
