A Realm Reborn Trailer and website

Final Fantasy unveils its newest online chapter in the series with a new trailer full of 'bay'sploions along with their website at the end. Actually what comes as a surprise to me is the Coming Soon statement at the end. I mean how soon could this be and why have they been keeping it secret until now?
My only guess is probably so it doesn't take attention away from their tech demo at E3.


Anyways enjoy the trailer!
