If this is covered elsewhere, my apologies. My question is really along the lines of when 5th edition is out, does it make the BTs invalid? With all the talk about new Space Marines, I"m just curious what if anything will happen to BTs?

With the "march" move and the fact that BTs have Righteous Zeal, does it make them a little overpowered? If I'm not mistaken, BTs are the only SM chapter to be able to take 20 man strong units, when you consider that you can now march them and RZ, that seems pretty powerful combo?

Anyway, just curious if Black Templars will go away or how they will be affected?
