October 1 release date is the following: "Metroid Prime 3: Corruption, the third installment of the hit trilogy, launches with motion-sensitive controls exclusively on Wii on Aug. 27."
Those of you with August 20th marked on your Exotic Wildlife of Zebes calendars aren't imagining that release date, Nintendo announced it (along with the release dates for a bunch of other titles) back in May. What has this lesson taught us? First and foremost, don't use indelible marker on your calendars, you should really know better by now. Second, just in case this is a simple typo we've contacted Nintendo for confirmation of the new release date. [Update: and they've confirmed the new release date.]
... stay strong.
