Well, it looks like Square Enix has decided to tease us a little. They have released the first screenshots from the upcoming mobile version of FF VI. It appears that the graphics of the upcoming iOS/Android title have been slightly tweaked and enhanced in comparison to the original version. The images show smooth, vivid graphics, which are pleasant to the eye, but in fact may look quite odd to some die-hard fans of the series, who are used to the grim, pixelated look of the original SNES version.
Unfortunately, there is no offical info about the release date yet. Rumor has it, that the iOS and Android versions should be out by the end of the year, but we wouldn't count on that, because Square Enix is famous for taking its time.
