We're designing and balancing raids so that the difficulty between 10- and 25-player versions of each difficulty will be as close as possible to each other as we can achieve. That closeness in difficulty also means that we'll have bosses dropping the same items in 10- and 25-player raids of each difficulty. They'll have the same name and same stats; they are in fact the exact same items. Choosing Heroic mode will drop a scaled-up version of those items. Our hope is that players will be able to associate bosses with their loot tables and even associate specific artwork with specific item names to a far greater extent than today.

Wait, WAT? I thought the entire reason 25-man loot was better than 10-man was because it was harder to organize 25 people effectively. At least, that's been the excuse in the past, as I recall.
