Well, good question, but I don't think so. Not really that big deal since the cinematic on Alliance and Horde's side is already released thanks to world first kills and circulating around Youtube. You can just look it up and bam, it's there.
It'd be cool if there was something like that. Not necessary, but it'd be cool.
Do you know how small the part of the community that goes to the forums like this one here? Extremely small. Most of the people I've talked to in WoW have no idea that Blizzard is even making new models.
