Because they've been talking about its ability to connect even when it's "off". This would be new to the Xbox. (The 360 does have the capability to shut down to a "low power mode" to *finish* a download it already started, but once it's off, it's off.)
Or, as I've said, there's a difference between "feature" and "requirement". I'm pretty sure we'll see that the talk and leaks about "always on" are referring to a *feature* (that the console *can* always connect to the internet, download updates, look for content, or whatever the heck else it's supposed to do -- what Fearon calls "always connectable") and not a *requirement* (that the console will refuse to function at all if it is not connected to the internet).
I really think all the kerfuffle is about hearing "always on" and jumping to the conclusion that it's a requirement.
Of course, I've been hopelessly optimistic before. When the facts come out (i.e., when Microsoft officially announces that, yes, they do have a new console), we'll know for sure.
The indefinite suspension didn't last very long for the Florida morning-radio hosts who played an April Fools' prank gone wrong—or right, it's kind of hard to tell—and according to an official at the local health department they also won't be charged with a felony.
I remember reading a story about the Kickstarter campaign from Chris Roberts, creator of Wing Commander and looking to create a new space MMO-type project. The results of his campaign proved there *was* a market, and he was starting to get investment bids from private investors as a result to further fund his game.
