My money is on Hysteria, sadly. Even though they play most of it during normal shows anyways. What they need to do is, mix up the songs not from the full album. If they do Pyromania, theyll have enough time for the 6 Hysteria songs. I'd rather see all of Hysteria, then some Pyro songs and some newer Post-Slang songs. Instead of just Pyro, and Hysteria. Then again, I'm not going so my opinion matters none.
