The "definitive" double CD from way back covered everything, so we definitely won't get anything new (mainly because the band weren't prolific, which they themselves admitted readily, and almost everything they finished ended up released). I guess the focus will be on new mixes - but I just can't be bothered with them. Nothing will ever replace the magic of the original version. Those new mixes are a waste of time - a substitute for creativity, maybe another way to wringle some money from the labels (no bad thing, if that's the case).
I wonder will John Foxx trot out 40th anniversary box set of "Metamatic". It was only re-released five times, and even the fifth wasn't completely full!). He can always find (or make) another two-minute ARP noodle - like that unforgettable classic "Approaching the Monument": four minutes of barely audible white noise! Where was that evergreen hiding for 38 years?! Sacrilege! Or, i'm sure, there is always a new "drum machine experiment" or an "early version"... Come to think of it, no early versions/demos/dub mixes of three songs from the B-side of the album ever surfaced. C'mon John, reveal, we want them! And surely those can constitute a 4th CD. And in five years' time there can be another box of 5 CDs, and so on. Money-spinning juggernaut!
Sorry, got carried away a bit...
