Not a wheel chair, but he is using a cane. I wonder if that's post-Bane effect, or if it's just to emphasize that Bruce has been worn down to old-man status before he even dons the costume again? There's no possible way they'll avoid the collision between the two that happened in the comic, but Nolan will probably change it up a little.
The theater a few miles from me is running a triple feature on premier night, so it's 8-9 hours of entertainment. I might actually do it. It's only like $25, probably only respectful movie patrons will go, and it locks down a seat for the premier of tdkr.
