I'd say Chappell Roan, Charli XCX, Queens Of The Stone Age, Beth Gibbons, Khruangbin, Girl In Red, Fontaines DC among the big names is already pretty solid. Not as strong as last year (that one was exceptional), but still good.
And yes, we can expect more to come.
But this is completely different.
It's not like they are saying 'oh, the tickets are going fast, let's remove some acts from our yet-to-be-revealed lineup'. Oscar was most probably never on the RW lineup.
Maybe they won't want to risk it because of Fender canceling gigs all of the time (mental/physical health issues). He's canceled another show yesterday.
Ken was incorrect more often than he was correct the last couple of months though. He'll definitely know something inside-y now and then (I'm guessing he receives press letters and so on), but he doesn't really feel like a very 'close to the fire' person. That 'artists postponing a year because of the wildfires' bit feels very bullocks.
Can't imagine RW sharing a big batch of names before Pukkelpop starts their ticket sale then. So it will be half Februari at the earliest if we don't het anything before PkP starts building their momentum.
