A few days back, I went onto the test realm for an hour or so. A couple of things I looked at were the new hunter pet skills and an engineering quest.
The engineering quest is simply the finishing of one that engineers had done way back, with the mechanical yeti.

I'm already working on putting the mats together so I can have a pet yeti on patch day. That is my favorite pet by far.
The hunter stuff was a little more involved. The new pet skills are for boars (charge) and gorillas (thunderstomp). After trying these out on the highest level creatures I could find, being mid-upper 50s, I'm not sure if I'll mess with it in the patch. The boar's Charge skill stuns for 1 second, which didn't seem to be a whole lot as I was playing around with the pig. It may be good in pvp, considering it could be used to save my fellows from a warrior who is bashing away at them. I may get it for laughs, but that's pretty much it. The Thunderstomp skill of the gorilla was slightly disappointing as well. Aside from the small amount of damage it did (about 170 nature damage), the cooldown was a little too long for my liking. I have yet to try the windserpent, but I might get around to that eventually.
One thing I did notice while trying out the gorilla skill was that a new animation has been given to Arcane Shot, a fun little firework, as you can see below.

Anywho, tonight was domo and rag night. I have been out of town for every Ragnaros kill up to now, so tonight was my first time to witness the kill. Below is a fun screen of the death.
