Their big kicks recently for releasing stuff seems to be 4e Dragon and Dungeon magazines, 3e Dragonlance, plus the recent 3.5 corebooks, and a smattering of 4e and 3e sourcebooks. They are close, about half way, to finishing up the Dragonlance set with the new module trilogy, Age of Mortals, the Campaign Setting book, Holy Order of the Stars plus the map packs and screen still to go.
For Corebooks we have B/X, Mentzer Basic, Rules Cyclopedia, 3.5, and the 3.5 and 4e rules compendiums. Still to come are the OD&D, AD&D 1e and 2e and the 4e corebooks and 4e essentials corebooks. They might go with the recent reprint core books next but they have been doing a bunch of 4e lately and they have the MM II and III, DMG II, PH II and III, and the Essentials DM Kit already out.
