Feels like a lot of effort for a festival to make up a fake poster and share it on their own official social media when they're teasing an announcement in a few days. I think that's what we're getting and the fact you can sorta make out some logos is intentional to build hype exactly as he has done in this thread.
I'm more excited for the lineup reveal for other festivals than the one I actually have tickets to. A lot of festivals seem to have announced earlier than usual, if they go too late i think people will go elsewhere but hey it is what it is.
