I've been anxiously refreshing pages all day to see if the Night Elf cat forms would come. In vain, apparently, as Zarhym has just posted to let us know that the forms in question will be unveiled tomorrow "later in the day," which probably means mid-afternoon (PST) sometime. In the mean time, we've got the other three sets of forms in the gallery below. What would your ideal Night Elf cat look like?
