When asking for clarification those with inquires were simply met by a nod. Square Enix has yet to make an official statement.

Right now this is still just a rumor but it's something I am really hoping gets around to happening. Seeing the videos of the remake after putting about two weeks of nonstop play into the original Chain of Memories so that I could play Kingdom Hearts II (I got them at the same time) was pretty cool, I really wish all of those "Final Mix"s and "International Version"s would make their way over here, can't let the Japanese have all the fanfare after all.
