According to a translation by Adriasang, Square Enix CEO Yoichi Wada hinted during a May 13 earnings briefing that the company plans to announce a new large scale MMO during this fiscal year, which runs through the end of March 2012.
Wada stated that Square Enix plans to
operate two to three MMOs simultaneously. Wada commented on the problems
plaguing Final Fantasy XIV, noting that "they're at the point
where they can see the target." Square Enix operates both Final Fantasy
XI and Final Fantasy XIV, and it's also worth mentioning that it's the
publisher of Wakfu, which is currently in closed beta in North America.
