Ella didn't participate in the last comeback at all. The remaining 5 did great and recorded what is arguably their best mini album to date. And honestly I've never believed that Ella would be coming back. And now that Satbyeol's gone... I still think Pixy will be all right. Don't get me wrong, I love Ella and Satbyeol, I already miss them and I will support them in whatever they do in the future, but I also love Pixy. It's OT4 now whether anyone likes that or not. The way I see it, people who write unreasonable comments or who just stop following Pixy were actually never really into Pixy.
There have been talks about one AllArt trainee joining Pixy. But even if she doesn't join, I'm sure Dia, Lola, Dajeong, and Sua will handle it just fine.

And yes, I already have my ticket for one of these shows, can't wait to actually see them live.
