If I had to guess...
HT: (4/6) Papercut, One Step Closer, With You (depends), By Myself (depends), In The End, A Place For My Head, Pushing Me Away (depends)
Meteora (3): Faint, Breaking The Habit, Numb
MTM (4): Wake, Given Up, Bleed It Out, What I've Done
A Thousand Suns (3): When They Come For Me, Waiting For The End, The Catalyst
LIVING THINGS (3/4): LOST IN THE ECHO, BURN IT DOWN, CASTLE OF GLASS, VICTIMIZED (depends)
Other (2): New Divide, A LIGHT THAT NEVER COMES
TOTAL: 19 / 21
If not all of these in the set, at least in rotation in varying sets. For example, I see Wake opening at least one set out of probably three on the tour. By Myself and PMA I feel depend on how the crowd reacts to them at Download, and how much the band jams to them. I really want With You to stay, but that also depends on how much the band is thinking about changing the setlists up. I see When They Come For Me returning on at least one set, the band loves that song. VICTIMZED might return depending on how many heavier songs from the new album they'll be playing. I think it'd fit nicely after GATS (if Rakim joins them for GATS, I imagine he could throw down something nasty over VIC). ALTNC is at least returning for Europe (if not all, at least in Portugal)
