3PP still producing 3.5 compatible stuff?

[Napftor]

We may not be the most prolific of publishers but Tricky Owlbear Publishing, Inc. is still going. All of our products are for 3.5 but we are now gearing up for Pathfinder (as well as some old-school adventures using Swords & Wizardry rules).

Since we started, our claim to fame has been the "Behind the Spells" series of pdfs which feature the backstories and secrets of D&D's iconic spells. The first 36 of these were compiled into the highly praised Behind the Spells: Compendium (also available in print!) We also just finished an 11-article run on KoboldQuarterly.com (Unseen Servant being the final mini-version of the series). I don't see this series (or the sister series "Behind the Monsters") moving away from 3.5 rules.

If you mean current Official D&D 3.5 stuff being available now (when 4th edition and GSL are in full play), the answer is a big resounding no; the D20 license is now fully 4th edition and will be for the foreseeable future.

With that being said, Wizards of the Coast's D&D website does have some leftover 3.5 areas still up and some of the digital-only Dragon and Dungeon back issues (before 4th edition was released) do have 3.5 material that you can still download.
