I got a demo of Systematic Chaos. I haven't gotten a chance to listen to the whole thing yet, but from what I've heard so far, it seems decent at least. First off, it's all instrumental (I believe...if not, then the majority of it is), so you get to hear a lot of Petrucci's work (which I think everyone will agree is the best thing about DT), and you don't have to listen to LaBrie's whiny singing. Its style kind of resembles ToT or SDoIT, IMO, but again, I have 6 tracks and I've only really listened to two of them, and bits of the others.
