Read what I've been saying...
It's not Square-Enix at all. It was a badly faked and poorly explained publicity attempt. Still, it managed to fool most people.
Thje fact that the beta(Anyone who calls the leaked version an alpha has no idea what an alpha really is) leaked just before the publicly announced release date is the icing on the cake, IMO.
the whole thing seems convincing to me. you say the beta leak is "icing on the cake"; what are your other supporting reasons for this being a stunt?
One of their members was in the RHDN IRC channel, trying to get everyone to post this everywhere. I was a witness to it as was Leno and a few others. Tried for around... a day and a half to get people to post this on myspace, facebook, digg, etc etc etc.
Nightcrawler did a detailed search(Not sure how ot phrase this... he didn't use friggin' google.) on the e-mail address and found it doesn't exist.
There are other things, some my poor memory are blocking off from me, some I'm possibly not at liberty to divulge publicly. I'm not sure, but I'm not gonna take the chance.
