How many years do you think the used vinyl market will be lively? And when will it start dying?

Do you think records will ever just dry up and dissapear? Will record shows still happen in 50 years and do you think Japan will still have 2000 record stores in 2054?

It seems the current turnover and interest is far too great for it just to die off.... but, how long will that last? Will it only take a new generation of "CDJs" and keyboard beat makers to drop off a percentage of the used/new vinyl market?
