Last week images of the Theatrhythm Final Fantasy box suggest that Nintendo Network will soon be launched.
The upcoming Final Fantasy spinoff will be have a wad of downloadable material, and publisher Square Enix had previously noted how some of it will be paid for. The inclusion of more paid content appears to be part of what Nintendo's calling "Nintendo Network".
The company already used the title for its E3 2011 content hub, so it seems that the shift towards more online play, sharing and communication with Nintendo could be forming the basis for a more robust system than the relatively bare bones approach compared to Xbox Live and PSN.
