Mark Sherman of AP has this brief postargument story, and Lyle has this post suggesting that the Court might reconsider its earlier decision not to take up the underlying question of the merits of the case. Of course, before they could get to the merits, they would have to resolve the state-grounds procedural question. On direct review of a state-court decision in the Supreme Court, unlike habeas, an adequate and independent state ground of decision is a jurisdictional bar. They can't just make an exception.
