Obviously everyone's concentrating on the look of the costume, but I heard Michael Keaton interviewed on WTF and some things he said gave me more hope for the project. He praised the director, José Padilha, and says his take is really interesting and timely.
Also, comments he makes about why he didn't return for the third Batman movie and also his choice of projects makes me think that he sees something of merit in this remake. He did admit that he took the part in Robocop (as the head of Omnicorp) partly just as a career thing, saying that as an actor you need to pop up in stuff from time to time that will play internationally. But he also said, that "if this works," the movie is going to be really interesting because of the places Padiha is taking it.
Obviously, take it all with a grain of salt, since a lot can go wrong with making a movie despite the best intentions of everyone involved, but like I said, it does give me more hope for the project. And, I'll be honest, I'm not as bothered with the new costume as much as everyone else seems to be.
