If you look at Freedom II in OP3 it has Wing Zero Custom-esque arm things so my guess is that both of those are going to bring up some sort of energy shield similar to the EA's MS they had guarding the Lohengrin cannon in Eurasia that probably only protects the front to attempt compensate for the loss of Freedom's shoulder cannons (those things on its hips are beam sabers. Also I think that in order to make up for the offensive loss they are going to give Freedom a cannon that is going to be a Buster version of Wing Zero's (due to the fact that the two beam rifles can be handled with the ease that Wing Zero handles its rifles) cannon with the power of a Lohengrin.
