The Reading / Leeds show will, I think, have one of two outcomes:
1) The band actually considers it to have provided a conclusion to that era of their career and doesn't play anything except PIB on the next tour.
2) The band realizes that the songs work live and the people enjoy them, and we get more Origin tracks next tour than we have in a while.
I'm worried that'll it'll be the first one, though.
Y'know, i'm pretty sure that all of the setlist issues that people have had could be easily fixed if Muse just extended their shows. At the Vancouver show on the TR tour, the setlist was kind of pitiful; 18 songs, a number that includes the Helsinki Jam. Next tour, they'll have 6 albums under their belt. They could easily do 23 or so songs and have time to spare for whatever jams and extended solos they want, and they'd be able to get in all the staples and a good handful of fan favourites.
