It is interesting that of the 11 pictures in the slideshow, there are 2 of Batman and 7 of the Joker! It thought this was supposed to be a Batman movie but it really seems like the villain is going to steal the show.

You could be on something here. I asked myself the same thing, but then explained it with the fact that I mostly get TDK news through the HHH thread here. So it's logical everything is focused on the Joker/Heath.
But after your comment, I did a quick google image search. Just typed "The Dark Knight" and looked at the pics coming up. The results affirm your thoughts.
Ok, that's not exactly rocket science (
), but it's still surprising.
