GMax can load them - you'll probably need a plug-in - not sure if it can convert them - I don't have WOW.
I'm picking up on the fact that WOW has at least 2 separate build versions - not everyone's copy of WOW seems to have the models in .M2 format - so, there is another potential option here to get a format which is more easy to convert - not sure how this affects option 1 (GMax) above.
Your third option is to keep tuned in to the WOW modding forums - you can bet your life that someone is working on convertors, coz some people live and breathe for converting model formats.
