The worgen pet is being looked at and discussed as we speak. Here’s a blue post by Zarhym in response to a question about the Garwal:

It is not intended that Garwal can be tamed while in worgen form and will be addressed via a hotfix in the near future. When we have determined how to handle situations where hunters have already tamed Garwal we will let you know.

On a side note, a Hunter in Dalaran told me earlier today, “It’s going to suck with Blizzard takes your badass pet away.” I simply replied, “It’s just a novelty pet for me at the moment. Nothing to get upset over.”

I still have Skoll to look forward to. 🙂
