I will happily bet a case of Möet that in twenty years time, more people will be playing through conventional PA's and cubes than will be playing through stick line arrays...

I remember exactly the same hype and drivel when Bose came out with the 802 type systems... 'Oh yeah... in the future, EVERYONE will be playing through these kinds of speaker systems...' 'It's the future of live sound', yada yada yada...

Well, maybe some 'alternate' future... You know, the one with the flying cars and the vast modern clean metropolises, with no poverty and shiny happy people holding hands....
