you paint a very bleak picture Alan.
where do you see the relentless reissuing / remastering of back catalogue stuff?
no sign of stopping and there's a relatively healthy market out there - albeit some releases being limited editions like Rhino Handmade / Hip-O-Select etc
It's a worst case scenario but it's a serious possibility.
I reckon that the reissue market is a symptom of the times unfortunately.
If there was enough good new music being pushed people would have less call to seek out reissues. It's a bit of a last gasp really.
If it all goes tits up that market will go the same way too.
