Well, as far as I know you can't tell for sure if a woman is pregnant till 5th week.
Till 12th week a pregnancy can abort naturally.
That's what she and her doctor mean by "not being in a stable period of pregnancy".
Kenji and her probably decided to marry although it would have been possible she's not pregnant in the end.
Either way, I'm happy for her!^^
She always wanted a own family and Kenji and her seem to be really sure (and happy) to found a family.^^
Though I'm sad I won't see her in concert next year. ;_;
But I waited for so long - some years more won't do much.
Please cancel the tour, cause I want the child to grow healthy and Kuu keep being happy!
EDIT:
JAPONESQUE release date officially changed to 01.25.2012!
It's up at her official site.
Also No Man's Land is the official song title, it does have the apostrophe now.
