It was announced this morning at GAMA - original Dragonlance co-author Margaret Weis' company, Sovereign Press, will be doing Dragonlance for D&D3. It's unclear whether this will be a D20 book requiring the Player's Handbook and published by Sovereign, or some kind of licensed deal with full rules and the WotC logo somewhere. The core book hits in the fall, and there will of course be supplements. The full announcement isn't up anywhere official yet; EN World has it for now.
