dubstep reached it`s peak already.
It doesn`t have the energy to be any bigger.
I don`t think it contains any advanced techniques either.
The general level of production quality is quite high for a music that has so much fire in it`s belly, but I would hardly say the techniques are any more advanced than what is happening in any genre.
It`s just another sub genre of music.
I like it a lot, but it`s not some amazing new undiscovered jewel.
