To sum it up:
Game saves, key configurations and preferences will be tied to your Steam account. This means that if you delete a game from your PC or move from one PC to another, you'll regain all of your saved games and configs upon redownloading the game.
I actually read about this in an interview like a year or two ago. Interesting to see how long it takes for them to make the features available for the public.
