Square Enix recently announced FF:Crystal Defenders for download, and it seems "Final Fantasy IV: The After Years" will follow.
It seems like the Japan-only mobile game FFIV: The After will head to download networks with a recent listing on the European Patent and Trademark database. Although not listed in its entirety, the trademark title is "The After Years".
S-E's European division recently told C3's Adam Riley that it would make an appearance on WiiWare (and presumably XBLA, PSN also), so here's hoping for more Final Fantasy treats worldwide.
