Patch 4.1 PTR: Caster legendary news and speculation

The story so far: At BlizzCon 2010, an enterprising questioner at the Quests and Lore panel asked if we'd ever see a caster legendary weapon that wasn't a mace. The response from Chris Metzen was that we would see a caster staff. We didn't really hear any more about the subject until today's patch notes for 4.1, which included this tantalizing tidbit:

For those wondering, a "camera bunny" is an object that triggers a cutscene in game or controls some camera rigging -- we've seen them before, particularly in Uldum. What this implies is that somewhere -- possibly in patch 4.1, possibly later -- we'll see the introduction of the caster legendary. Since the bunny is located in the Caverns of Time, it's a somewhat safe assumption to make that we'll see it somehow incorporated in the Caverns of Time: War of the Ancients raid.

Currently, there's no information on when that raid will be released, which means this may just be preliminary information added to prepare for a future patch -- much like the pre-Shattering events were seen on the 3.3.5 PTR, well before the Shattering actually occurred. Regardless, the last time we saw a proper legendary caster staff was Atiesh, the staff wielded by Medivh and only available for a very short time to raiders that managed to collect the pieces from Naxxramas 40 before the instance was removed completely with the launch of Wrath of the Lich King.

While it's unlikely we'll see a return of Medivh's staff, the location of the camera suggests that perhaps the staff we're going to see in game originates in the days when Azshara reigned and Azeroth was still one complete continent. If this is the case, then what we're going to get is something we've never seen in-game before. Is it a staff belonging to Azshara? Cenarius? We don't know, and we won't know until we see more information. What do you think the staff will end up being, and more importantly -- whose dead hands are we going to have to pry it from in order to obtain it?
