Yesterday we reported that Final Fantasy X's scenario writer had stated that Final Fantasy X-3 was a possibility if there was demand. With Final Fantasy X/X-2 HD Remaster now available in Japan, numerous spoilers from the Audio Drama have been leaked.
According to the Audio Drama, we now know that Tidus and Yuna aren't together anymore, although no details about this are revealed. We are also introduced to 2 new characters, Chuami and Kurugum, with Chuami stating that she's Auron daughter. The most surprising reveal is the fact that Sin is back, and Yuna will once again set off to bring peace to Spira.
Although Square Enix didn't officially confirm Final Fantasy X-3, Kazushige Nojima's words, the Final Fantasy X-2.5 novel, and this Audio Drama, really points to a Final Fantasy X-2 sequel. Final Fantasy X/X-2 HD Remaster will be available in North America on the 18th of March, arriving 3 days later, on the 21st of March, in Europe.
