Not that this will stop the countless posts like "but how will we level up so we can go to Northrend" but Outland as we know it now will be as we know it in WoD. It is not being revamped, removed or changed. Draenor is Outland as it was before it went boom and is linked to our present timeline via the soon to be red dark portal. They will exist side by side just as Northrend and LK are still doing their thing even though he's long since dead.
