Nintendo of America president Reggie Fils-Aime has explained that the Wii U launch window is launch, plus the following three or four months. Reggie wouldn’t confirm whether or not Pikmin 3 will be on the system at launch, but it is within the launch window.
IGN: Actually, regarding Pikmin, is that launch, launch window, is that some time off in the future…?
Fils-Aime: So we’ve said that that’s launch window. Everything that we’ve shown from a first-party perspective is definitely launch window.
IGN: And launch window is the first couple months? Something like that?
Fils-Aime: Eh… More than that. It’s launch plus the following three to four months.
