Let me explain what these rumors mean for those who don't seem to understand.
Always Online: This DOES NOT MEAN you HAVE TO BE ONLINE in order for the console to function. All this means is that the console can be kept always online in a low power state so that you can download updates/patches/new games remotely without having to turn on the console. Eliminates wasted time when you come back to your games to find updates waiting.
Play from Optical Not Supported: This DOES NOT MEAN you do not need the disc in the tray. Nor does it mean used games are blocked. As of this time, it simply means that you must install all games and they play from the harddrive at that point. No info regarding whether the disc is still needed for license checks or whether the disc will only work on that one console/account after install. Even if it does, I don't care. Like Kitler said. You get the benefits of digital distribution content, without the drawbacks of needing to download the game or having to have a fast internet connection.
Kinect Required: This DOES NOT MEAN that every game has to use it, or that you even have to use it. All it means is that you have to have kinect plugged in for the console to function. Probably because of the deep integration with motion/voice controls that will be usable should you so choose. This is a non-issue.
