Interesting items in the data files

I've been looking through the Wowhead latest additions page, and found some interesting-looking things. Caveat: some of these are probably datamined, we may never see them in game, etc. Still, it's fun to look at.

• Intravenous Healing Potion. This does the same thing as Mage-summoned Conjured Mana Strudel (except for the whole group), and shares a cooldown with food. Despite the name, I'd say this is not meant to be used in combat. And based on the medical-themed name, I'd say it's probably going to be created via First Aid.

• Wintergrasp Commendation. Apparently bought with marks from Wintergrasp; the interesting thing here, of course, is that these are bind to account (BtA), so you can effectively PvP on one character and send honor to another. Does this open the door for my much-coveted BtA badge-type tokens? I hope so.

• Ghostly Skull. This small pet is apparently sold in Dalaran for 40g, and it looks awesome, in my opinion (see screenshot above -- the skull is in the top-left corner). I will be getting one as soon as possible on my DK. Tacky? Maybe. But I don't care.

I like that Blizzard is going in a lot of different directions in LK; this really seems like more innovation than it was from classic to BC, from items to class skills to world environment. I'm sure there's more cool stuff that I've overlooked. Have you come across anything interesting, either in the beta or on the various sites?
