I think they are waiting for Hinata's 2nd single to release before they announce Keyaki's 9th single. This is the first time Sakamichi has two groups under the same management. Right now, Seed & Flower has been focusing on promotion for 2nd single. Hinata's first year doesn't have a national tour like Keyaki's first year, so they are going to be seen a lot in variety shows and music shows in their first year. The first and second year are the most intense years as full-time idol. Nogi went through it, Keyaki went through it and now Hinata will go through it as well. Keyaki is now in a state where they are becoming more popular and being more comfortable with larger audience on a bigger stage. Their first time pitch at Jingu Stadium is an indication of that. They are going through their 4th year which is supposed to be preparations for bigger things in the coming 5th year when celebration of 4th year strikes. They hit a new record for Keyaki Republic this year. 48000 attended in three days. 16000 attended each day. Last year 15000 attended and in three days 45000 have attended. If you look at Abunakkashii Keikaku performance Takahiro-sensei changed choreo to two front dancers as Hiichan and Pon were synchronized. That was my whole impression with the group they are more synchronized than ever before, despite have breaking the "all 21 members".
