I liked Mark Ruffalo in The Avengers and think he could carry a Hulk movie if done well. I never saw the Ed Norton Hulk film, and I find Eric Bana kind of boring, as was the entire movie as a whole.
I too am looking forward to Dark Knight Rises, but I think I'm just more looking forward to the finality of it all. I just hope the hype is worth it and we have a truely epic conclusion. Of course this being Christopher Nolan, I expect that to be the case but I can't have my expectations too high just in case there is some disappointment.
