Iwata talked about a perception that Nintendo's deep pockets create an unfair playing field for third-party developers making games for the Wii or the DS.

The system--seven years in the works--will digitally distribute first-run, AAA games from publishers like Electronic Arts, Take-Two, Ubisoft, Atari, and others, all at the same time that those titles are released into retail channels.
