I’ve created a table to shows which opinions have been thus far released in the term based on sitting and majority author. You can find the table here. You can find the .xls data here and the .numbers statistics here.
It’s hard to make too many predictions right now. Justice Kennedy will likely write the opinion in Melendez-Diaz (November) because Justice Scalia wrote two opinions from the January sitting. This chart will become increasingly useful as the Court hands down an avalanche of cases between now and the end of June.
