I am not saying that the Wii will not be awesome, I still believe that Nintedo will win this console war. But it seems clear to me that the Wiimote cannot 'detect its exact location and orientation in 3D space' with 'pixel-perfect accuracy' with the technology it was using at E3. Perhaps it still will. Gamers like me want to know what the Wii will and won't be able to do.
In an interview with IGN, Perrin Kaplan was asked (4 minutes in) "Are we gonna see more hardware surprises, are you still hiding stuff?" to which she answered "YES! next question". Matt - "Still hiding stuff? Why are we still not seeing all of the hardware features?"
