Armor Cores and new ones to come

with the starter core and then the Halo Reach core, I just personally feel the armor is getting dull. I was a fan of Halo 4-5 armor cause it fit the sci-fi look I so love about this game.
Will there be any future armor cores that branch out to look like that?

I think armor cores should be removed entirely so we can mix and match armor pieces and coatings.
