You can read the announcement here. I can only guess the meaning from the page through not-so accurate translation, and it's supposed to be about separating the staff members in the current company I think? The page also mentioned about the difficult economic situation right now, which makes me wonder if something dreadful has happened to the company financially.
For the customers:
これに伴い、現在お申し込みをお受けしている作品群(レジンキャスト製着色済み完成品モデル)は、全て販売終了となります。
All current pre-orders of colored completed model made of resin cast are to be terminated.
And that includes this upcoming Perfect Change Shulawga I believe?
Scheduled to be released by the end of this month, Shulawga's product page is not updated with the information from the announcement though. Information about pre-ordering this item is still there.
However, the termination of all pre-orders mentioned above might be postponed if there are a lot of orders going to the company right now.
We really need more information to know what exactly is happening at Studio Halfeye. Fans please stay tuned for more news.
