Re: The Joker sized elephant in the room
I always felt (and justifiably so, seeing as Nolan has stated so in interviews) that each film tries incredibly hard to be it's own film, meaning plot, theme and even visual style differ in each film and there is little to no reliance on previous plotlines to fully enjoy the film. I'd expect maybe a mention or two about the jokers actions and the aftermath, but i seriously doubt they'd linger too much on the joker outside a mere 3-5 second mention.
I wouldn't even want anything more than that.
