There's a fairly strong likelihood that "nothing confirmed" can be taken as "nothing announced" in this instance. They've probably got shows planned out, but not ready to announce for whatever reason.
Unfortunately, I have come to accept that whatever they're doing next year, it doesn't involve Glastonbury. Just the complete absence of chatter about it suggests that one or both sides has decided that it doesn't make sense.
I’ve been desperately wanting this to happen for now this 3rd Glastonbury while they’ve been reunited but him saying ‘nothing confirmed’ makes it even more unlikely for me as it suggests they’ve always been set for not coming back since the reunion started.
Like surely if they wanted to do Glastonbury it would have been confirmed ages ago.
