Speaking to VideoGamer.com, Halo 3: ODST producer Alex Cutting said that the Halo series will only incorporate Microsoft's motion-sensing Natal "when it makes sense." Cutting noted, "We're going to make the games we want to play," adding that the company "will definitely investigate it," though he didn't elaborate on any plans Bungie might have.
Regarding the feasibility of Natal control for first-person shooter, Cutting says that many doubted console FPS play before the advent of dual analog sticks. In other words, there's room to see controls evolve again. Cutting concluded that he wouldn't "bet against" Natal, saying, "There is a lot that can be done with it."
Joystiq readers will recall that Bungie boss Harold Ryon stated earlier this year that he "absolutely" thought Natal could work in Halo: Reach. Given Reach's likely proximity to the Natal launch, and Halo's massive following, we don't think it's reaching too far to assume it will incorporate the device in some way.
