BOF have some info from one of their long time sources. It seems there is the possibility that Batman will be utilizing some type of aerial vehicle in Chris Nolan's upcoming threequel..
“One of my sources mentioned the possibility of an appearance of [an aerial Bat-Vehicle]. The more I thought about it, the more sense it made with the planned shooting locations. Could be interesting!“
Of course when we think aerial Bat vehicle we thing The Batwing. But I think if this is legit, Nolan will be going a slightly different route. Given that this will be Nolan's last bat movie, I don't doubt that he will be stepping it up in every respect, and that includes Batman's rides! I for one think this is on the level.
Their source also says that after the destruction of the Tumbler in the last movie, we will be getting a new redesigned Batmobile. But then, I think most of us take that as a given anyway!
