A sparse teaser page has been posted by Square Enix Japan that appears to suggest an announcement concerning Final Fantasy V and Final Fantasy VI is due this week.
A teaser page containing little more than sprite outlines and a date of January 17 has been posted on Square Enix's Japanese site.
According to Siliconera, the sprite outlines are those of the Behemoth from Final Fantasy VI and what appear to be character sprites from Final Fantasy V. The only other information on the teaser page is a date of January 17, which is Thursday this week.
Last month, Square Enix confirmed that Final Fantasy V "and more" will be ported to iOS devices. Is this part of the "mobile revolution" that the trailer spoke of, or something else?
