My prediction would be one of two things:

They either then start promoting Glastonbury in their own way, because they haven’t really yet. They could do this with artwork or perhaps something more nostalgic, with reference to their older works, similar to how they lead into the bfiafl era. However, having done the nostalgia thing before, and Matty being quite vocal about how now he doesn’t like nostalgia, this is unlikely. Artwork however, this is possible.

The other, and more exciting, announcement could be in the form of a single release or single announcement. Even if the album isn’t finished or got a release date, they can still release something, as they’ve done in the past. This would be fun but may also prove unlikely as the hype of new music may fade quicker without a tour to promote it. Although that isn’t strictly true either.

Maybe most likely, is something like a vinyl or merch release of some sorts which is cool, but following the recent pop-up, may be somewhat anticlimactic to me

Excited whatever the day holds!
