[1] Do you think that 2010 is remarkable for her?

If she decides to change it up a bit from the last few years, maybe.

[2] What do you expect in her 50th single?

I actually think (for some reason) that the release will be brought up somehow so avex can cash in on it sooner than Ayu would probably like. Like some sort of 3 singles in 3 weeks deal or something.

[3] If the releasing pattern is not the same as 2009, when do you want her 50th single to be released ?

Maybe autumn. Been a while since we had something that wasn't spring, summer, or winter related.

[4] What do you expect in her new album?

In the next month or so.
