I wonder what they're gonna do with Chaewon and Eunbi, because they'd slide into the group perfectly. But that's still more than a year away...
We'll see how it shakes out but I feel that having the group debut like this now and then adding the IZone ladies once their exclusivity period is over is a better strategy than a lot of companies did the first time around with the IOI members groups. Although they probably shouldn't hard commit to anything about that yet and give themselves some flexibility rather than announcing that Chaewon and Eunbi will definitely join later.
