I think it'll be much harder to get tickets for 2023 than before.
I don't think media coverage this year in itself will have much of an impact, as there is always huge media coverage, and people wishing they'd be able to go.
But it is now a much broader festival than ever with much wider appeal - for instance, it now has a credible breadth and depth across more genres especially this year for urban/grime/rap (e.g. Megan Thee Stalion, AJ Tracey, Kendrick Lamar headlining), and teen-friendly pop (Olivia Rodrigo, Sigrid, Holly Humberstone, Billie Eilish headlining).
Also, there was 2 consecutive "fallow" years due to COVID. And given what seem like more complaints about over-crowding than usual, I think they'll keep the capacity smaller.
