I think we can all agree to this, because it's obvious.
The Sony motion controller does everything that the Wii Motion+ does on an actual 1:1 ratio.
On top of that, it does everything the Natal does because it also uses a camera. Obviously face recognition is within possibility, even though they did not mention it. And even though the Natal doesn't require a 'mote, I don't see anything the Natal did that is beyond what the PSEye can already do. The team was right, sometimes you just need to have buttons to make things work.
Please do not forget that the technician said very clearly 'Let me remind everyone that this is only an engineering prototype, and the design will change'
We can all agree to this can't we?
