It would be reasonable to have skins that look exactly like in the comics, but this is NRS, so you'll get the same answer as to any question about an unreleased game: Nothing of the like was fully confirmed, everything we can tell you, you can find in the same videos we have seen. We don't know.
I remember having the Batman Beyond skin Arkham City, and they made those moves work. I think he had some kind of small under-arm wings of some sort. And it only came out for the glide. Still no cape.
