SMG, Dual wielding?

I dont know if the SMG is returning but why wouldn’t it? Reach didnt really have any good UNSC CQB weapons. only ones were covenant weapons.
Personally if the SMG does Return I would like for it to have two different types: The “Silent type” and the regualar one but maybe with new additions. but that has to mean one thing to come as well, Dual wielding and from what I’ve heard Dual Wielding isn’t returning:(

If the SMG is to return how would you want it to look?
