Nintendo of America president Reggie Fils-Aime has revealed that all of the first-party games shown at E3 are 'launch window' titles, but that doesn't mean they'll be released on day one.
In an interview with IGN, the Ninty boss said that by 'launch window' he means "the launch plus the following three to four months".
He also talked about the future of Retro Studios, the team behind Metroid Prime, whose last game was Donkey Kong Returns in 2010. "Rest assured, the team is hard at work. But I'm not gonna tell you what they're working on."
