Hate to be a nag, but could we discuss the MS conference in the MS thread because I also think people are way underestimating what was shown for Kinect.
Edit: Forgot I wanted to say something about the Cafe.
I was thinking that it might be possible (as someone else mentioned somewhere) that the screen on the controller could be used to eliminate icons from the screen, and I was thinking how cool that would be if no game was ever interrupted by a button icon, then I some of the demoes at MS's conference made me reconsider because of the "press A to change weapons" and the button icons for performing actions within a cutscene.
Now, the weapons thing could be solved with a Stone of Agony type of deal where when you step on an available weapon, the controller rumbles and you look at the screen to see which weapon it is.
The cutscene buttons however, present an entirely different challenge, now I don't actually think Nintendo is going to announce this, but because of how one holds a controller, if each button vibrated independently, you would be able to find them quickly through the vibration pattern, and a quick glance at the screen could also tell you which buttons. I think the delay time on most of the button pressing events is long enough for a person to figure out what they need to press. I suppose they simply just make the controller rumble every time they want you to look at the screen, but I like the idea of separately vibrating buttons.
