There's a short feature in Nature News that reports the publication of a paper by Matt Tocheri (Smithsonian) and colleagues in tomorrow's issue Science. This is the published version of the paper Tocheri presented at the Paleo meetings this year, in which they presented an analysis of the wrist morphology of LB1 (H. floresiensis), which they show is very different from that of modern humans. If LB1 was microcephalic, this would be somewhat unexpected, so this paper overall lends support to the "hobbit as separate species" camp.
The Nature News feature also includes some comments by Dan Lieberman and Robert Martin about the discovery. Check out also this interview with Tocheri about the paper.
