I think Christine herself is going to want to record something. It's clear she's glad to be back in music, and wants to make up for lost time.
I have been wishing she'd record that blues album for decades, but realistically, I think the most likely would be BuckVie II. I think she's entirely capable of recording another album with Lindsey. It's clear they are pleased with the album, and it has received a good response from both critics and fans; there's no reason on earth why they shouldn't do it again. I don't think Fleetwood Mac as a 5-piece will be doing another album, and that's fine with me.
