Support leaks

Hey I wasn’t sure where to ask this question, but I see a ton of people here with this opinion and want to ask if I’m missing something. I was very strongly under the opinion the idols were next and Astra Yao wouldn’t be for multiple patches away. But I see so many people thinking she’s next and I want to know why? Almost every leak I’ve seen has made it sound like she’s barely conceptualized yet, and isn’t even fully confirmed to be playable. Meanwhile we have had so many leaks about the idols. And we know there will be an ice support, which makes so much sense they would be after Miyabi. Just wondering why this isn’t the common opinion? And if I’m missing something, to be directed in the right place. Thanks!
