There will be two of them, both of which have been seen (an armored one at the Comic Con and one in the famous first pic with Batman). However, the newest detail is that the armored batsuit has Kryptonite all over it and it can shoot missiles.
Also, there are two types of batmobiles, as well as a third flying one.
Lastly, a shot with a shirtless Bruce Wayne was already filmed, but not to show the audience Ben Affleck’s incredible physique. Instead, it shows the superhero overlooking a destroyed city, most likely Metropolis (or, who knows, maybe Brainiac will appear from Batman v Superman: Dawn of Justice and will lay siege on Gotham… wishful thinking?)
