n-Space confirmed that there will be a DS version of GoldenEye, and it will be developed by them.
Activision announced a new GoldenEye game for Wii during Nintendo's press conference, and today, n-Space announced that they're working on the DS version.
"One parting announcement," n-Space said on their Facebook. "At E3 this year, Activision and Nintendo announced GoldenEye as a Wii exclusive. Not quite. We're happy to confirm that a DS version is in the works at n-Space. More on this next week!"
n-Space has previously worked on other first-person shooters, including the Call of Duty DS games and Geist for GameCube. They were at E3 representing their Tron games for Wii and DS.
