Assuming there is a CW Spring Tour 2026, there would be a schedule conflict for Ciara.
So I'm also wondering if Tara is coming back at some point. I'm guessing no one knows for sure right now. 
-Ciara is shown in the tour promotional photo. But that’s just a differently coloured version of the White Christmas Symphony Tour photo, so I’m not sure if that means much.
-Ciara could leave BIIRD, similar to how Caitríona just left ANÚNA, but Ciara seems to be quite essential to BIIRD’s existence, so that seems unlikely.
-It wouldn’t be that soon if Tara came back to tour in spring after having her son in August, especially if she takes him with her.
Part of the difficulty with figuring this out is that both Tara and Ciara were on Nollaig: A Christmas Journey. If only Tara were on the album, it would seem more like Ciara is just here temporarily, and if it were only Ciara, her membership would seem more permanent. Instead, we’re caught in this confusing middle ground. I wonder if it could just be scheduling conflicts with Tara’s son being born in August when they were recording or if this is hinting at something deeper.
As you said, probably no one really knows right now. I just like overanalysing things
