The Art of Remasters?

Listening through the Art of Noise tracks on my media player I can't help but notice a missed opportunity. ZZT seem to continually recycle the original early material from '83/'84 (and boy do they milk it) whilst China seem content to let the bulk of the bands back catalogue languish.

I only realised how little of the Art of Noise's music is still being issued when a box of my CD's was 'lost' during a house move some years ago. Trying to replace their albums via eBay became a surprisingly annoying and expensive chore (thankfully cut short by the idiot who took my CDs into "safekeeping" finding them some months later). Having just scanned eBay I can see only one copy of "In No Sense? Nonsense!" on CD and one exorbitantly priced copy of "Invisible Silence" listed.

So why don't Warner Bros or whoever own the rights reissue these albums? There is lots of additional/bonus material from 12" singles and b-sides hanging around and there are plenty of fans ready to buy shiny new masters of their favourite 80's albums. If ZZT can spin out one albums worth of material into a 2 CD retrospective, a 3 CD box set, 2 expanded reissues and a "Best of", why can't we get the 12" version of "Legs" on CD?
