"Unfortunately, it's not that it's not impossible for us to develop Final Fantasy 7 for mobile," Tokita told Shacknews. "It's that currently, space will be an issue. Phones won't be able to contain the space it takes. It's over a gigabyte. People are probably going to have to wait a few years."It is unclear exactly what Tokita is referring to in stating that "it" is over a gigabyte, and thus whether any work has actually been done on the project. A number of current App Store apps do, however, come in at over 1 GB, although as The Verge notes, a recent PC re-release of the title checks in at over 3 GB.
Tokita announced plans to bring Final Fantasy VI to iOS devices this fall in the prior interview, which follows the release of various Final Fantasy games over the past few years on iOS. The last title from the series to appear on Apple's platform was Final Fantasy V [Direct Link], which was released by Square Enix this past March.
