This is a welcome surprise, if you're into old Final Fantasy games. Square Enix has just confirmed that Final Fantasy 4 is coming to iPhone and iPad this December 20. An Android version is slated to hit at some point in 2013.
Final Fantasy 4 mobile appears to be a port of the Nintendo DS re-make of the game. It's re-make that saw 3D graphics added to the experience, as well as other tweaks, features, and enhancements like, say, mini-games and a new translation.
Japanese gaming web site Gamer has the first screenshots of the iOS version, take a look:
