Early on, when Natal was just announced, I thought (based on marketing descriptions) "Hey, this could really be something new and cool." Now, seeing this 'lineup' of games that I guess are supposed to appeal to us gamers, let me say this: Natal is destined to be as gimmicky, useless, and not-developed-for as the PS2's Eye Toy was.
Why? Because of one simple thing: First impressions. First impressions matter. A strong launch title can make or break a system, i.e. HALO and the original XBOX. "Pioneering" (hah!) peripherals aren't exempt from this.
