2004 topic, so reply at your own risk. ;') The July issue of "Astronomy Now" (a British mag, which is six months behind on its website) discusses the Nemesis theory in a breezy two page article (plus a couple pages of illustrations if memory serves), and Mike Brown doubts that Nemesis exists, but also entertains the possibility of some large body (such as the one discussed here) having been the agent for putting Sedna where it is. Brown's idea is, if more than one body like Sedna is found, orbit-wise, then it makes Nemesis more likely.
