Well, some people aren't sure, but looking at this quote from the BBS Ultimania:
When I read that, my first impression was that it would be a remake or a compilation or something that wouldn't require too much work or pr, because if it were going to be a brand new title, Square surely wouldn't plan to release it the year they first mention it. The people from marketing would know how to build up a bit of hype etc. It fits well if it's directed at the foreign market; that means of course it wouldn't have been hyped in Japan at all.
So, Re:Coded fits the bill, I think. Wouldn't take as much time to produce and doesn't need as much hype as a brand new title.
Hmph it looks like your right. Darn it was really hoping for a Mickey game.
