What? Why would you want to plug your PC into a television? Not only is that already possible with the right sort of TV, but a good monitor can have just as good, if not better, resolution than most TVs.
A gigantic screen. My friend's brother has played computer games on his 40+ inch HDTV. It is very impressive. I'm not quite sure how this article indicates anything to be alarmed about.
Other than Bobby Kotick's unbearable $15-million-bonus face.
The screen is bigger, but it usually not as high-res as you could otherwise get. The only difference is you have to sit farther back and the need for a larger space in which to park it. A good computer monitor will cover just as much of your field of vision as a good tv monitor, no matter the size. The "1080p" touted as being a wonderous thing is 1920x1080. Checking on newegg, a TV like that would cost you on the order of half a grand. A PC monitor with that same resolution (higher dpi, smaller size) I saw on there for $150. Same veiwing experience, less room required to have optimal viewing distance, and less expensive. That is why monitors are better.
As for what is scary about it, the article title. "Kotick to be new best friend of the PC?"
Also what Karne said. "Streamline interfaces" just means idiots can do what they want, and those who are more
advanced competent not-pants-on-head-retarded users can go take a hike. A hike through the horribly designed "advanced" menu which now contains everything which used to be easy to find[1].
