I'm curious if Nero will have different guns and devil arms (weapons) to go with his different devil breakers. I wonder if the devil breakers are meant to be his version of styles, which would be great, or if they will be an excuse to have less guns and devil arms for him. Alternitely, cartridges could potentially be used in all 3 of his weapons to change their effects and create options.
My biggest hope is that all three characters have equal amounts of options, since that has not been the case since DMC2.
