POA - They might remove this, though somewhat seems unlikely. Pts.OF.Athrty was a single so I think they will have HT version to support that single. Besides, they played it at every '09 show which was mainly singles
SIB - They won't remove this
LFY - Was a radio single. Doubt they'd remove this
FTI - Yeah more than likely will remove, despite being a single in Europe
Session/Wake/CFTI - Doubt it. They'd use some of these as intermissions or intros
LOATR/SOTD - Singles off the most recent album? Not likely to be removed
HHH - The song itself is basically gone for good, but the verses over Crawling intro or a capella may still live on.
Why? Papercut, APFMH, DS were never played in full in '09 (Papercut verse 1 over BIO, APFMH verse 1 over POA outro). They're as good as gone... maybe not Papercut. Not sure what to make of NMS. It's never been dropped and was a strong MTM song but never was a single.
I think most songs are 100% not going to come back...
Forgotten has higher change that FRGT/10.
HTF/ETR won't come back
TLTGYA makes YOU "Zzzzzz", not US.
Not likely.
