Arguably I think we should've gotten one for each film, because TF1 had a ridiculous amount of awesome concept art. I remember there was one that was planned for release after the ROTF that would have concept art from both the first and second films, but then it just kind of disappeared. I assumed we would get one after DOTM encompassing all three films, but I haven't heard anything about such a book. Anyone know whether or not we're going to be getting an Art of the Films book for Transformers? To be honest, I can't believe they haven't put one already.
