Because its defined so largely by one instrument (wobble bass) and very formulaic patterns, I can't see it hanging around too much longer. Although every genre has its bright spots, and I do like the tamer interpretations on it (SBTRKT, James Blake, Burial, etc..), its clearly a trend that people will move from.
What worries me is that electronic music has largely become the common denominator for everything young people are listening to. Not to be snobbish and hate, as a lot of what I like now a days is based around it, I just feel that music is the most disposable kind of music ever. No one will be playing Dubstep in 2015 and beyond.
