No official announcement, but Square are definitely working on the sequel
After visiting the Square booth at E3 and seeing this autumn's line-up - FFVIII, Chocobo Racing, Chocobo's Dungeon 2, and the recently released Ehrgeiz - people were encouraged to sit down in Square's small theatre and watch a finely edited montage of the Japanese company's line-up.
Right after the fifth game, Chocobo's Dungeon 2, a small, apparently mistaken event occurred. The screen went blank and then about 10 seconds worth of images flashed across the screen. The images were of full-motion video of the sequel to Parasite Eve.
Square officials had no comment on the (obviously planted) 15 second movie slice, but could only say that the game may come out in Japan in the future, smiling and winking all the while.
