Square Enix boss confirms Final Fantasy Versus XIII still in production | VG247
yeeeeeeeeah. There still is hope!
The executive took to Twitter to describe the rumours as a hoax.

Wada said he attended a regular meeting on the RPG’s progress today, and that fans would be surprised to see how the game is shaping up; he specifically mentioned the city setting.

Final Fantasy Versus XIII was announced over six years ago as part of the Fabula Nova Crystallis sequence; an expected reveal earlier this year was unaccountably delayed. We may hear more on September 1.
