Tom Goldstein at the SCOTUS blog:
There is very little information that can be gleaned with confidence about the authorship of the remaining opinions from the Term.
It does look exceptionally likely that Justice Scalia is writing the principal opinion for the Court in Heller â€“ the D.C. guns case. That is the only opinion remaining from the sitting and he is the only member of the Court not to have written a majority opinion from the sitting. … So, thatâ€™s a good sign for advocates of a strong individual rights conception of the Second Amendment and a bad sign for D.C.
It would certainly be nice if he’s right.
