I can give you my impression after 1 minute of work: it doesn't work -- it crashes. I'll be sticking with X1 until the bugs with X2 are addressed.
Btw, some of the bugs in X1 made it into X2, e.g. in PRV, when you add tracks, all of the controllers (128 of them, I think) appear at the bottom. Cakewalk had acknowledged that this is a bug, but have managed to preserve it in X2.
