Muse going dubstep?

Maybe you've already heard one of the tracks of Muse's new album "The Second Law".
I really don't know what to say about the song "Madness": I really like it, but it's not really like what Muse used to sound like. Personally, I think it's because of the "wub- wubbing and dub- dubbing" in the song :) But I think it's a different kind of dubstep, it sounds more like "acoustic-electro-dub" (I don't really know how to explain that, haha)

If you have listened one of their new songs; what do you think? Has Muse gone dubstep?
