DiZ is already on top of the skyscraper.
Oh dear, how did I not notice that?! Then again I think it's just part of the building, but hey~
On topic, yes I agree, this would make a great cover, but it's not really symmetrical / suitable as a cover. To be honest, it pretty much sums up the game's perspective in one accumulative shot, encapsulated within Nomura's artistic style, but it would probably be found within the game case, not on it.
I'm sure we'll get something equally, if not more appropriate as a cover. I've loved all of them thus far, and I'm sure I won't be disappointed this time either.
