I believe the eventual goal is to release updates to all the combat forms and trees. Bears were already previewed, now the cats are just being released. They may not get all the form updates into one patch, but give them some time.

The forms really aren't drastically changed, mostly warpaint and the color changing to match your hair color (not sure if the forms can be a different color than your regular hair, but that might be an option). Otherwise they mostly look and act like they did before. All their mouths are supposed to be able to close now, as opposed to always gaping open.
