I'm no expert, but with my friends who are really into that music, they said last years line up completely smashed it. As you say, be excellent for all of us if it continues to grow in popularity haha!
Sorry haven't been keeping up, are they replacing the rabbit hole with something bigger as well - that might draw more people? Arcadia growing too (I guess) is a good thing too, and will be a draw for people as it's new. So all in all, seems they're trying to address the problems!
