Do you wish there was a new suit because you don't like the look of the TDK suit? That's fine. But if you want a new suit, just because it's a new movie, I think that's kind of silly.
Not silly at all.
With these Batman films the suit and "new toys" evoke the feel and imagery of the film. It establishes the identity of the film just like the logo and colors of the movie.
- Batman Begins (first suit, Tumbler)
- The Dark Knight (TDK suit, Batpod)
- Batman Returns (new suit, Batskiboat/Batmissile feature)
And the Schumacher films doubled this with suits, gadgets and vehicles galore. I don't know, there's always room for improvement and cool gimmicks. The film batsuit has been evolving since it was created in the late 1980s and has yet to be perfected.
I know there's the new Batwing vehicle, but I feel like there should be a suit in here somewhere.
There's a great sense of excitement in the early stages of these Batman films where they release the title, the new actors involved and then the new suit and bat-vehicle. I remember the disappointment when it became known that Batman wouldn't be sporting a new suit for this latest film.
Remember the feeling of seeing these for the first time?
That's the "identity" for Batman in Begins and then Batman in The Dark Knight. TDKR doesn't have that "feel".
Spoiler: 
Very true
