I mean, yeah, we have the PH units currently. Plus the couple of Nurgle and World Eater units they've produced. That said, you know as well as I do that it isn't the same thing by any stretch of the imagination. In it's accessibility or in it's price. Alas, that's not what this thread is about, so I don't want to further derail it.
Needless to say, I do like Unbound rules for cross utilization now. :) SW TWC Juggy Riders, BA AssTroop Raptors, etc
