Cool. Your choice. It happens. I stopped playing a lot of games when they ceased to hold my attention. I know I'd love a graphics update, item system overhaul and the rest.. but if they keep releasing story and gameplay I enjoy, I dunno. I'll be around for a while. Come whatever may all the false hopes in the world won't change anything but your own disappointment.
That wouldn't be a tease though. If they outright declared that the NPC was the ONLY instance of that gender in the game, the problem would entirely be with people making up their own incorrect assumptions.
