REQUIREMENTS: Luckily, the Xbox One won't require a constant connection to the Internet, but there's a possibility that some of the key features wouldn't work as well or at all. The Kinect system is required and will come with the machine, rather than sold separately as has been the case with the Xbox 360. The Xbox One also will feature privacy settings so it doesn't feel like the Kinect's camera is always watching you.
LIMITATIONS: Xbox 360 games won't work on the Xbox One because the underlying technology is different, according to Microsoft. Microsoft was vague about how the Xbox One will handle previously played games bought from other gamers, though it confirmed used games will work somehow. There had been talk that Microsoft might restrict used games on the new machine.
GAMES: What games? Despite the fact that such titles as "Call of Duty: Ghosts," ''FIFA 14" and "Forza Motorsport 5" were teased during Tuesday's flashy presentation, actual games weren't available to try out afterward. Microsoft said it plans to focus on Xbox One titles at the E3 conference, which starts June 11.
The Xbox One shows promise with a sleek shell and a new Kinect detector that seems to perform fine — at least if you don't try to confuse it with too many people at once. But the lack of games is notable, as are lingering questions about what it can do without an Internet connection. There are too many questions about the Xbox One, even after experiencing — not just hearing — what Microsoft has planned. At this point, it's too early to say whether Microsoft or Sony is leading in the latest round of the console wars. They'll have to duke it out at E3.
