I was thinking that maybe, assuming they do have Mac Hudson as alive, that they'll upgrade his suit in a few ways. Here's my thinking:
The Guardian suit hasn't changed ever, and we've seen it torn apart twice lately by Northstar and Postman Mike. Besides, he may be one of only 2-3 survivors of Postman Mike and has a daughter to think of.
So why wouldn't he thicken his garb by a millimeter or 5, increase the power and dynamism of the forcefield, cut down the suit's offence (no more concussive wave as it's no better than the e-m blast, it just takes up space without adding anything), and increase the suit's durability and life. Right now the suit seems to poop out pretty fast in battle, he'd fix that problem!
- So a better force field
- more endurance
- keep the electromagnetic projectors, down beam pulse, flare (but lessen the energy available for it), ultrasound beam, graviton beam, and a dispersal beam (maybe drop it, it sounds superfluous given the rest of the suit's capabilities) but drop the concussion wave.
Maybe they will, maybe they won't.
