Actually, the Hello Kitty UI interface is faction-agnostic. And I'm not sure how HK would voice her allegiance anyway -- she has no mouth and she must scream. Regardless, Alice over at Wonderland links to two separate instances of a Hello Kitty-themed interface forWoW, one of them from famed virtual worlder Joi Ito. As she says, "Bloody hell ... it's horrible :o)"
If Blizzard released an epic set of Hello Kitty armor tomorrow, how many of you would jump at it?
