I belive the way foward for this sound is for it to get a deeper edge to it but I dont make this side of techno and personaly trust the likes Arkus,Boris,Sven,Amok ect to take it in the direction they choose they do have the right of course to do what ever they want with it and seem to be the leaders in this style.
Like I say I trust them to push this sound onwards I know one thing Ive seen it rock a good few dancefloors.
