While they've got a really great opportunity to beat Amazon by being more open with their content, something tells me they're going to screw it up royally with DRM.
Both Amazon and B&N are distributors. That means publishers are their customers too, and they're a hell of a lot more fickle about DRM/no-DRM than those who buy books... hence, B&N has a lot of publishers to lose by including weaker DRM than the Kindle.
