I'm really elated that Blizzard is updating the models, in fact, this subject will probably mean nothing to me since I will be enjoying the new character models rather than thinking about this.
But, at hand, Blizzard stated that they will take a look at Worgen and Goblin models in the future... Blizzard, you MUST look at least at the worgen. Since they decided to change how they looked at the last moment because of whiners, they are completely broken and seem unfinished. I mean Goblin look waaaay better and are almost on par with how Pandaren are done. Worgen have the same cheesy gimicks used on Vanilla and B/C models but with nicer textures and broken/ugly animations and features.
I hope they get them fixed, they seem so broken to me and I was most excited for them in Cata.
Anyway, not a big deal I'm looking forward to the other models and will forget about Worgen for a long time.
