Just to bring some facts:
New Songs on setlist:
The Requiem/The Radiance
Wretches & Kings
Iridescent
Jornada Del Muerto
Waiting For The End
Fallout
The Catalyst
Songs That Left The Setlist since last tour (2009):
Session
From The Inside
Somewhere I Belong
Points Of Authority
Leave Out All The Rest
Shadow Of The Day
Hands Held High/Crawling
Based on this, and considering they played "17" songs (considering the requiem/the radiance as just one), i guess we will have around 2 or 3 coming back, and 1 or 2 added into the mix.
I would say Crawling and POA may be coming back soon. as for something not listed, it could be Burning in the skies, When they come for me or Papercut or it seems like that.
