Did a quick Google check.
Producer and director of the Japanese MMORPG Naoki Yoshida gave Xbox owners a glimmer of hope in a chat with us during the E3 trade show in Los Angeles. Through a Square Enix interpreter, Yoshida told us that the company is in talks with Microsoft over the restrictive Xbox Live rules that currently prevent massively multiplayer games from working across platforms. If successful, the game will be released for, at the very least, the Xbox One.
From the article I found. So IF the article is true and accurate, it's a possibility. Yoshida wants it to happen it appears, it's just a bit of a fight trying to get it to happen.
