That's the question though - why would the band be working on nothing? Reason implies they are working on something. How that time is spent is up to them. We can only guess and suggest. The comparison is a flawed one - they are doing something, and I'm not alone in thinking new > re-hash.
Going by this logic, what if they
had worked on a new album and had all the tracks written and recorded, but decided to re-record a song or two from the debut album "just for the hell of it?" The implication here is that they would be used as
bonus tracks; something a little extra for the fans who have been with the band since the beginning (or enjoy their complete catalog).
As cool as it would be to hear the entire debut album re-recorded, I'd definitely rather have something new. I think most of us would.
Wait, lol. We've had the re-recording songs from the debut conversation before, but what DG tracks would you want redone and why? So they can replace Miller's excellent work with another layer of rhythm guitar? Or so Russell can sing his parts an octave lower?
As far as my comments about re-recording a track or two from Damnation Game, I wasn't talking about the proggier tunes, but rather songs like the title track and Dressed To Kill. These are heavy, hard-hitting songs that aren't terribly different from the more recent style of the band. I definitely think a re-recording of The Edge of Forever or A Winter's Dream, for example, would kill the charm. And yes, I'm sure with their style as of late, Romeo would destroy these songs by adding more rhythm guitar parts, burying the bass in the mix. No one wants that.
At the very least, the band could play one of the heavier tunes from Damnation Game live. They could easily swap a shit song like Electric Messiah for Dressed To Kill, for example.
I feel like IC has more of a "balance" to it (what I mean is, whereas on DWOT and TIO I felt a few songs were just downright lackluster, this one seems pretty consistent, not hitting any real lows nor huge highs in terms of quality until maybe towards the end of the album; make of that what you will).
I definitely agree that the last two albums have been more consistent than most of their past efforts. Like you said, the best songs (hell, a
lot of the songs) from their earlier albums destroy anything on the last two albums, but those earlier efforts did contain a bit of filler. Maybe I'm alone on this, but aside from a few tracks (LUTN for sure, possibly Electric Messiah and Lords), there's little filler on Iconoclast. Instead, you have filler
parts spread throughout most of the tracks (Dehumanized verse, unnecessary WAIL solo, keyboardless Heretic bridge, etc.), but never enough to completely butcher any of these songs.
