When I was paging through the original 4e core books, I couldn't help but think how there was a strong possibility that you could play the game with some well-crafted random charts and no DM. Oddysey recently pointed out to me that there's a section about that very thing in the back of the DMG.
And apparently WotC is seriously pursuing that idea.
If you follow the Amazon link, the cover they show bills it as a "board game" and not an adventure for 4e, so it my be an extremely watered-down version of the core rules, simplified into a Hero Quest type configurable board game. And it looks like the "interlocking dungeon tiles" are flat, so not the 3-D pre-painted terrain I'm predicting will herald the final vanishing of the virtual tabletop.
