Two cameras definitely makes the whole technology that much more acceptable. It's like trying to view the world with one eye. Not banging on people who only have one, but the depth perception that binocular vision entails gives Natal the leg up over previous iterations of monocular tracking. I'm still a little spooked by that Milo contraption though. Having an AI talk to you is nothing new, but this level of interaction is pushing it. That was staged to an extent, but still.
