From Guy's page:
Q: Re Mark’s coming album, are you allowed to say when it’s scheduled for release? If you are allowed, but don’t know, what would be your guess?
A: No, I’m not really allowed but as with every album that is at this stage, there is no schedule for release. Sorry but you’ll have to hold your horses for a while.
It's seems they're not exactly in a rush. Maybe because there's no touring involved? So, what's a likely release date? Autumn 2023? Earlier, later?
