Yeah I have to say (in my professional opinion as a game developer), most of those patents are wishful thinking or out and out bullshit.
For example this: "Why not take a picture of yourself with an included camera and have your features actually appear on a game character?"
Which is fine, and would be a great idea had not everyone in the industry been trying it for the past ten years, and failing miserably, because of the simple fact that nothing of that sort will *EVER* match up with the art in a game, unless specifically tailored to do so, or the capturing mechanism is something more sophisticated than camera based techniques can provide (i.e., 3D surface scanning, which isn't feasible for home users anyway).
And this: "Intelligent Audio Mixing Among Media Playback And At Least One Other Non-Playback Application."
Too bad it's been done before, so WTF? Big deal.
Not to mention, I personally find it hard to believe that many game devs would really want to invest in making a game for this thing, when the device itself could potentially fuck the user experience through no fault of the developers.
