If they really do this I'll see them adding 9/10 further tracks to the setlist. They know many people only come for their greatest hits and for the new album so they don't wanna disappoint them with 6 old tracks.
One Step Closer, Crawling, In The End, Somewhere I Belong, Breaking The Habit, Numb, Given Up, Bleed It Out, Shadow Of The Day, What I've might be their biggest hits. And this is just a rough list. You can easily add many many more songs (Lying From You, Points Of Authority, No More Sorrow, New Divide...) to it.
We'll see. Just playing 6 classics would disappoint many people. But I doubt they'll do it anyway^^
