^^ interesting outlook on the future there mate
its certainly within the realms of possibility I will say that
but i would also say that while poeple still fall in love with bands and artists they still want to 'own' a piece of them and to most thats getting the cd or LP from the store
even now, I find myself (as a 100% downloader these days) that when i ask my friends this question they surprise me by saying they still buy all the cd's of their favourite artist's
definetly still viable as the best way to promote yourself at gigs etc..
