The most recent issue of Science has a series of articles on a couple of new skeletons of Australopithecus sediba. This is a recently described species from the South African site of Malapa at about 2Ma, discovered by a team let by Lee Berger. The authors have argued that A. sediba may be a link between gracile australopithecines and our own genus Homo. I haven't gotten a chance to wade into the several articles in any depth, but for now here is a link to the summary article by Ann Gibbons on the Science website. There will be more posts on A. sediba as I get a chance to read these papers.
