Will IZ*ONE soloists be able to sustain their current "success" as the Produce and IZ*One effect wear off?

Most of all Produce groups have good sales at their debut, but as time goes by the hype dies down and they eventually stagnate. Do you think they will maintain their hype as time goes on? Will they eventually have more variety appearances and become closer to household names? Will there be a Chungha, Somi or Daniel type soloist in IZ*ONE?

Wonyoung will likely retain her popularity one way or another. Not necessarily as a soloist or even in music.

There will probably be at least one more that can maintain a high amount off popularity over the next 5 years (Sakura).

What about the rest? Will Eunbi, Yena, and Yuri maintain their debut level success? Or Chaeyeon who we've yet to see what her next steps are, or Minju who's slowly preparing for her acting career
