Adobe has not published an official time frame for the next release of Director and generally does not disclose details of new releases more than 30 days before a product is expected to ship. However, our current planning assumption is that the next major release of Director will be announced in January 2008.

From the recent Adobe Max videos, it doesn't look much chop anyway. Since Adobe has been so focused on Flash, AIR and all the other funky development tools, Director is looking very lackluster at this stage.
