Outdated character models

After the release of Cataclysm we got the new races and they showed us what Blizzard is capable of in terms of the way characters look. Standing next to a human character, it just looks like it's from a different game. Also, some of the animations on the older models look just terrible (not that the worgen cast is good, looks stupid).

I understand that the models should not be completely redone, most of them look pretty nice. The models are a unique part of the game and make it what it is, but they should just be brought to line with the newer races. Make them more detailed, add some more customization options and (maybe) adjust some animations like night elf and human casting, they just look really clumsy.

Idk if Blizzard has said anything regarding this recently, but let me know what you think
