Pretty hard to disagree with any of the above. Most of it is already happening. Digital is just continuing to explode year on year but, conversely, and on a vastly smaller scale, the right titles are still worth releasing on vinyl.... just. You have to do your sums very carefully before you commit to a vinyl release as a 100 unsold records can make the difference between commercial success and failure and that's a very tight margin of error. Plus records are bulky, heavy, awkward items to store, distribute and sell as the costs for warehousing, transporting, shipping and posting are all rising massively. I think vinyl will continue as a semi-viable format for a good few years yet. Prices on records across all genres have plummeted downwards over the last 10 years (apart from super-rare high value items) and that trend will continue as the baby-boomers clear out their collections. Luckily, a lot of the volume is being taken up by younger collectors who are finding great value items on vinyl plus they seem to like the cache of lugging vinyl around. There is also an upsurge of interest and buyers from other parts of the world and emerging countries like Brazil, Chile, Russia etc. So there's quite a bit of life in the old dog yet.
It's difficult to counter the technological revolution because that fuels everything. Who wants 78's, cassettes or 8 track cartridges these days? Also, space is becoming a major issue. The influx of population to the UK and other factors are suddenly putting a huge premium on house and storage space. The big collections of the future will probably be in the hands of the few people who can afford to store them properly, i.e. have a spare room or two, and that will become increasingly expensive.
If I hadn't decided to 'prune' my collection down to something more manageable around 10 years ago, I'd have been in real trouble when I recently moved! 12"'s and Albums are now down to around 20% of what they were 10 years ago whilst singles are hovering around 80% of what they were 10 years ago. And the wife still moans that there's too many.
It's the CD's and Hard-Drives which are becoming a problem now.
