Justice Sotomayor has this "Statement ... respecting the denial of the petition for writ of certiorari" in Wrotten v. New York. The case involves the Confrontation Clause implications of testimony "via a two-way video that enabled the testifying witness to see and respond to those in the courtroom, and vice versa." However, the case isn't final in the state courts, so SCOTUS kicks the question down the road.
