That's an excellent question to which I do not have the answer.
The website still shows information about the audition, and we know they are supposed to start performing on October 1st.
So the only members we know about are the draft members + Kitarie and Yukirin.
I guess I'll post a little about the draft members since not everyone might know about them.
Both of them were in Baito AKB while it lasted, and elected to apply for the 2nd draft, which began shortly after the end of Baito AKB.
Nishigata Marina is 19 years old, and is a Kojiharu and Matsui Rena fan. She's pretty funny? That's the little I remember about her.
Ogino Yuka is 16 years old, she's a good dancer, she likes Yuihan and Tani Marika.
Other known members are Kitarie (permanent member, captain) and Yukirin (concurrent membership with AKB48) which I'm sure everyone knows about but I'll share a couple of things while we wait for the 1st generation list...
Kitahara Rie is one of the only 2 members to ever fall out of senbatsu during the senbatsu elections to come back at a later year. She was in senbatsu for four years (the first four elections) and in undergirls for 2 years (5th and 6th) to come back at her best rank ever in the 7th election. She wrote the lyrics to one of Not Yet's songs. She's originally from Aichi, the prefecture of SKE48 which is probably why she was granted a (slightly short lived) concurrent position with the group in 2012. When her concurrent position was cancelled, Matsui Rena got mad and upset about it on stage.
Yukirin auditioned from Morning Musume's 8th generation and did not make it to the final stage. She also auditioned for AKB's 1st generation auditioned and failed, but tried again for third gen and made it. She can play the trombone and drums. She is THE AKB gravure queen above all others. She held a concurrent position in NMB48 for about a year. She had a huge scandal that management totally ignored
She has been in senbatsu for every senbatsu election, starting in at 8 and 9, but then staying in the top 4 ever since the third election. She was second only to the winner last year. She's a huge Morning Musume fan, and a huge fan of Ishikawa Rika whom she got to interview once. She has covered some MM songs in her solo concerts and some AKB events
