I undoubtedly will.
I'm not buying in to Anima Tactics until they come out with sufficient miniatures for me to play a faction affiliation list, though. I'm waiting on Church at the moment.
Your going to be waiting a long time. You do know that each faction will have a very limit selection (about 10 minis). That will probaly take two or more years to get that many for each faction. You can get a light faction army going and that will give your army more varity. Unless you plain on using the same 4-8 minis every game you play which is what you'll end up with if you only collect faction based troops. In infinity a good selection of troops for one faction will cost about $200. For that amount you can buy 10 light factiion minis and then save the other $100 for the 10 specific minis that belong with the church. Then you can switch between playing a light team or a church team to spice up your game play.
For me, I want dark and wissenchaft minis.
