I think 100% chance Octavarium will be played again and will be played soon (anniversary coming up). Not sure about The Glass Prison, but hopefully it returns as well. My biggest wish list songs right now are Octavarium, Voices and anything from the first disc of 6DOIT.
I agree re 8VM.
As far as a wish list, mine is really short.
- Anna Lee: This is relatively low on the list, but it'd be cool to see.
- SDOIT: I've seen ATC, SS, ATCR and LT/GF. I'd love to see the whole thing.
- Vacant: Like Anna Lee, it's low priority, but it'd be cool.
- Wither: My second favorite song on BC&SL, and I'm really surprised it hasn't been played more.
- S2N: My #2 song on DOT.
- Transcending Time: Thus far my favorite on View.
Of course, there are songs -- like 8VM -- that I've seen before and would like to see again.
