I suppose but when you look at the upcoming timeline:
13 dates in 2026 - I'm working on the assumption most of that will be a slightly revised setlist to get back into the groove, with maybe a new single thrown in; at least for some of them.
Album five drops, tbc when exactly.
UK/EU tour - Spring 2027
Biggest ever dates, UK stadium/s - Summer 2027
That doesn't say 2028 to me, it says 2027.
Then I guess to pay devils advocate - you'd imagine they'll continue for the rest of 2027 - probably U.S circa September/October (I say that part with hope, cause I'll go to a few).
At that point - they could even continue it, if the had eyes on anything like Asia/Australia, and all of a sudden Glastonbury 2028 isn't that far away, in the grand scheme of things.
All that to say - I don't know, tbh.
I think it'll tip over for sure, £410. Still incredible value for money, I paid 300 odd quid per ticket for Latitude this year (we go there with the little ones) which makes glasto the bargain of the century.
I think I caught some of PISS and SLAG at the Ritual Union festival earlier this year. Won't bother seeking them out again, there will be far better bands to discover.
