I think we will get some info with the North/South American tour announcement which should be around six months before tour start.
Fair point, and I hadn't think about that.
Let's say the new album tour starts in September 2021, it could be safe to say we'll get at least a title/cover artwork/concept reveal around early next year.
But... that would mean announcing a new thing before the Legacy era is officially closed... And judging by the way they worked with those things, announcements and stuff, over the last years... It sounds a bit unlikely, to be honest. Then again, it's also true they lost a full year of plans, and 2 different tours in the same year could be very likely, at this point. We'll see..
