According to this week's issue of Dengeki Magazine (via FF Reunion's aibo and the generally reliable NeoGaf Forums), Final Fantasy X-2 may not come with all of the International Edition content it originally had. Producer Yoshinori Kitase is reportedly considering whether or not to include the Last Mission content of the game, saying that he believes this segment to be a very different component from the rest of the game.

The Last Mission was a segment of the game where X-2 protagonists Yuna, Rikku, and Paine meet up again several months after the end of the game to explore the recently discovered Yadonoki Tower ruins. The Tower has 80 levels and a boss battle for every 20th level.

If it isn't released, it'd be safe to assume it could debut later as DLC, although that isn't common for HD remastered titles. But this would be too good to pass up, right?
