i wanted to see more about the new camera. Obviously it borrowed a lot from Kinect but does it really let the dual shock double as a move controller? i mean what can it do now? does it do the voice processing that Kinect does?

They didn't talk about used games at the meeting, but it won't block used games. I was kinda scared this rumour was true

to counter the 70$ game price statements i saw:

in CNBC interview, Sony's Jack Tretton says games for PS4 will range from 99 cents to $60. Can devs set pricing?

devs can and will set nothing. Publishers will set the prices as high as they think they can get away with.
