What do you mean 'dystopian'?
Well I guess the first thing I should say is that my interpretations are personal, I'm not trying to say that they necessarily reflect artistic intention or mindstate or anything like that (they in fact definitely reflect my personal mindstate when in attendance of dubstep nights of late).
I mean that the feelings I get from his newer tunes resonate as a negative reflection of society (or possibly micro-society, e.g. rave). So wheras say (an obvious example) to me Anti-War Dub is eutopian in that it focuses on positive aspirations for society, on the creation of better ways of relating to one another (and at one point I think it actualised or reflected that within certain spaces - i.e. dmz/dubstep raves at that time were literally demilitarised, plur, on a level etc), the feeling I get from the new stuff I hear is quite the opposite... i.e. it feels like a reflection of very grim circumstance.
The feelings I get from that new techy stuff are alienation and atomisation... my understanding of dystopia (maybe more accurately anti-eutopia). Miracles has those similar feelings, but there is still (maybe) kind of a hopeful tone, or at least I feel that I'm left hanging onto something, but say that really big tune with the third drop that no-one ever expects, it feels much less so...
Dystopian or bleak are not in themselves bad things, often incredibly interesting in art (probably more so than eutopian!), but I find it a raw pill to swallow cos not many musicians have made me feel so positive about possibilities as he has.
Having made all of the personal qualifications, I think there is something significant to be said about how this all relates to the themes which come out from the narrative content of his tracks, conceptions of Babylon, unity, roots etc
