I think Kibou no Wa is boring, until I watch the performance in Budokan (acoguissimo3), you should watch it too!
Family-related songs might be included, because well, it's related to graduation I think, I'm totally curious about the tracklist, I really hope she will do at least one cover song like this one.
I think this song is quie popular for graduation? No?
EDIT
From her blog:

She will be promoting this album with a tour. Compilation album with a tour, well..
Also, she mentioned that other than graduation-related songs, she will pick some songs related to encounter and farewell, relocation and moving, and anything related to those. So we have a clear idea about the songs now. (Which means, probably no new song at all.)
