I also have a full UCM army which I will probably start playing again after Gencon (I've been prepping my Shaltari for Gencon, and Larry has been gracious enough to help me prepare), and I've also quietly started a small Scourge force.
I am definitely going to stay away from PHR, and while the Resistance has a few cool units, they haven't really grabbed me. Also, I suspect a few people will want to play the Resistance.
