I hear you, its kind of an Arkham design for each game, the long ears are very reminiscent of Tim Sale's "The Long Halloween" arc back in 96, great design, but when you think of how many times Bats would be in an air vent, I can see them getting in the way.
I myself was never a fan of the Nolan series, having been a comic guy before the movies, but I can see the appeal, I just couldn't take Bale as Batman, great actor, no question. But after so long you have an unobtainable idea of who should play him. Anyway.
I think the upgraded suit in Arkham has been designed to incorporate the new batmobile, with the ability to be jettisoned at high speed. Plus I think if war has broken out in Gotham then heavier armour must be a no-brainer.
The armour from Asylum was awesome, hope there is an alt-costume option...... wait, of course there will be. How else would they make a Season Pass, there isn't any multiplayer
There have been confirmations that the Batmobile will have different skins. So you never know, there might be an animated series version. Lets hope. Not sure how they would incorporate the battle mode. Off the top of my head, I could guess that there may bee different versions that are select-able from the Batcave,
