Interestingly, I'm pretty sure it actually debuted, at least in the anime, three days ago... and quite possibly before. At least, stateside. Kinda pushes the question if this is really necessary.
Still, it seems a bit silly that it's just now being announced when I'm fairly sure at least 95% of fans know about it already, if not from the animated series, then from third-party sources, or possibly even owning one already. Still, at least this should mean we're getting an event fairly soon.
