Over at YN@LJ, a poster links to Nitta-sensei's post here.

Nitta-sensei announces the upcoming publishing of the last chapter of Haru (in BBoy Gold - which probably means #8, the tankoubon #14 will be out in the fall 2009 although the date is not set yet) and apologises for her wrongdoings, the long wait and thanks the readers for their support and mails during her hard time. I am not sure whether this means that Nitta-sensei is back - as I read it, it seems as if she is allowed back only for this to finish Haru. There is some talk about all her manga being pulled, and of the delay of the next BLCD in the series. Maybe Geri can shed some light over my wonky translation?

ETA: I've gone over the info that seemed most important again and got it to something like "Essentially, at this point in time the intention is to end Haru o Daiteita drawing the last part (in exchange) for the long support recived from the reader-sama (who are able to) distinguishing between right and wrong. The full/ended work will come with apology and gratitude."

Sounds like this is the end, both of Haru and of Nitta's work.

OMG! I so don't want Haru to end!!! *wails*
