People hate change, and Microsoft is changing things, but it's for the better. People have to understand their cloud integration. The cloud is really a bad name for it since it's somewhat of a buzzword, and most people don't really grasp what the cloud is anyway. They're going from 15,000 servers to 300,000 servers this year. That means where ever you are and whatever you're playing you'll have a good multiplayer experience since everything can be on a dedicated server and not p2p.
Please watch the following video where the Giantbomb guys talk to the Respawn team about Xbox One and the cloud. It's already cued up and it lasts for about 3 minutes.

It's really an advancement in gaming, not just what you see on the screen, but the infrastructure behind it. I know it's tough to filter through all the PR talk, and MS has not been good at all getting information out there, but they are going in the right direction. Also don't worry about losing your games, now that the xbox and ps4 are using x86 architecture, I would bet that's what any future consoles are going to be using as well, which means easy backwards compatibility. You'll still have used game sales, you can share your games with friends through the family sharing, and even "gift" games to friends (which means you can sell direct instead of going to Gamestop).
