I doubt they'll switch to H2A. The armor is completely different in that than in Halo 4. They could try to pull some Reconstruction "Do you still have your old suit of armor?" stuff again, but I highly doubt they will.

It'd be cool if they use it for something though. Maybe utilize some greenscreens or something to have them in their Halo 4 armor while in a H2A set.
