I think she'll release a new single (hopefully physical not digital) by the end of the year...she has to attend the year end shows and if she just sings MW for all of them, that's gonna suck. As much as I love the MW performances, I want to see something new. I certainly hope she won't release a new album by the end of this year or early next year. Ideally end of next year would be good with a few singles before that. I'm still hoping of A Complete arena tour next year.
...or she'll go weird on us and release a mini album with all new tracks with no singles before that by the end of the year/beginning of next year.
...or no new single...MW all the way for all the year end performances
edit: I don't think having a album soon means its gonna be rushed...after all, ayu only released 1 single this year...and all this time she's just been touring, doing a few magazine shots, cms, calendar, etc. This year feels like its the least busiest year.
