The upload was an accident, but it's illogical to think that the creation of the site (especially the big black and blue FF13 logo banner) was an accident. Even if there was a slight possibility that the english site got "mistranslated" to Japanese, the image of the logo is in Japanese and there's no "errors" there.
TBH, I expect FF13 will be released 3-6 months after the PS3 version(in Japan). If they're going to make the game run on the 360 for the US/EU, why not release an already finished product in Japan. Sure, the sales may not be on FF's usual scale and the hardware increase may not be as much as the PS3's release, but why not take advantage of the 1 million Japanese xbox users?... after all, 25% of the HD market in Japan consist of 360 users.
