I figured this would be a handy reference, a calendar of releases.

These dates are subject to change. They are based on shipping lists from http://www.diamondcomics.co m">Diamond Comics as well as some other info and some guesswork based on past releases. They reflect the day that these books will probably be released to stores, and subscribers may receive them earlier (or, later).
