It looks like Square-Enix have already finished coding their new US official flash site, before the countdown has even finished. Even though they only launched it today, we can already see what Square are planning to put on the official site by decompiling the flash. Thanks to our forum member byoushinn who has done just that, it looks like Square are planning to post an official trailer when the site is launched. We assume this because two files called "ff13-trailer-sd.flv" and "ff13-trailer-hd.flv" reside hidden in the flash. Unfortunately they aren't accessible yet.

It's impossible to say at the moment but it could be a new trailer. Maybe Square-Enix's countdown might be more than just a site opening. Don't get your hopes up though. They could just post the E3 2008 trailer again (the last one to be released for free). In any case, it will be the first full trailer to be officially released in HD if the second filename is correct. To keep an eye on the countdown, visit the US Official site through the link below.
