And I definitely agree.
I picked this up from an Edge.com article about Microsoft's potential plans to drop the standard pad in favor of using the Natal as a full time human interface.
Dan basically says that there no plans to implement such a control scheme - and that's a good idea. I'm floored by Natal, I think it's an amaziong leap in control devices. At the same time though, even if Natal were used to play a game like Halo, you would still need the controller in hand in order to fire your weapon. Used in conjunction, the camera system/controller combo would be an awesome gameplay experience.
