Why won't Microsoft talk more about.......

well you CAN plug a ps4 into the xbox one
so I do not see why you cannot plug the xbox 360 into it

Later in the presentation, when Panello discussed the Xbox One's ability to snap applications to the side of the screen during gameplay, he said "any application can be snapped to a game…this could be the live TV feed, so if you wanted to be playing Ryse and Killzone at the same time, you could snap that."
 
So with this snap feature, we can literally play anything of the PS4 on the Xbox One?

Saweeeet.
 
Like others have said, it will be coming. They do need to get out there and educate people on the truth, there's lots of misinformation out there. I know people who own 360s but don't follow things closely who still thought that X1 had the old drm policies in place. The hardcore gamers are out there looking for information, but the casuals aren't.
