Blizzard has confirmed today that the new druid models will be going into the next major content patch for World of Warcraft. They are releasing the form previews a little bit at a time; today's first preview (above) is of the Tauren's bear form. The bottom middle is the old form: you can definitely see the improvement - although it looks like we'll still be stuck with open maws. Here's the interesting thing: it's based on night elf hair color or tauren skin tone. Says Blizzard:

There will be five different designs for each of these forms for the Horde and Alliance. Night elves can choose to change their cat and bear look at any time by visiting the barber shop and changing their character's hair color, while tauren will be able to change which look they use by switching skin tones in the barber shop -- a new feature for tauren in the next major content patch. Given that there are more hair colors and skin tones than unique form looks, some colors and tones will overlap with these new textures. The hair and skin colors chosen will, wow gold in most cases, correspond with the color seen in the look of each form. Some similar colors that may share a particular cat texture will not necessarily share the same bear texture.
