D&D Fourth Edition with Virtual Tabletop

Announced at GenCon earlier this year, the 4th Edition of Dungeons and Dragons will include a virtual tabletop program where you can model your character in 3D and move him across a virtual map and roll virtual dice. I find it interesting that the characters are modeled in very static poses (to reinforce that they are miniatures) and slide across the map while rolling of the dice utilize a physics engine so they interact with the tabletop in a very realistic way. I also find it intriguing that their map program, while providing light sources for the player chose not to include any walls. I almost feel as though they're reinventing this product again, considering that Baldur's Gate did a pretty good job of including a very good scenario editor.
