Thanks all, I forgot about TOT.
It'd be interesting to see if they keep revisiting "classic" albums for anniversaries, but considering they skipped Awake (well, they played the last five songs, but not the entire album) and FII, it certainly isn't a given.
I'd love to see them play Six Degrees in full, but the length would certainly be prohibitive. At least I&W and Scenes allow for a full first set of additional material.
