Please don't spread false information, typically a Japanese game is announced in Japan first, and then an announcement is made for the rest of the world some time after. This has been the case for every other KH game released. Misleading title, no where in the article does it state that Kingdom Hearts HD 1.5 Remix will be "Only for Japan".
To quote from a fansite, Shamdeo, who has proven to have a strong connection with Square Enix NA
"This by no means implies that a localization won't happen."
