let's make something clear;
there really hardly is anything bronze to see in the trailer [perhaps the belt, though we'll have to see more to be certain], and indeed in the supposed suits that are shown [ all three together ], there is indeed no 'bronze' on the knuckles and gauntlets etc.
i was simply reffering to the promo art, which without a single doubt did have bronze accents. Remembering somebody shown a cosplay suit of the supposed new batman suit, that one actually did have these EXACT bronze accents [thought it was bright golden in the cosplay].
meanwhile, i started wondering whether it might finally do come out in the movies but ever so slightly faded and desaturated, even though i forget about the shown fiberglass/resin models which had zero brass.
going back to the promo art, regarding the 'mech suit'......obviously first of all, it's straight out of the comic book representation and it's totally awesome. I also realised, that it looks - offcourse - very armoured. I kinda feel the previous Nolan suits kinda look like skinny versions of this suit, though not as well executed.
What i'd like to see is how the mech suit looks like without the white glowing eyes. not that there's anything wrong with that, just curious.
