iOS 7 On-Screen Tutorial

Do you think that once an iOS user updates to iOS 7, that there will be an on-screen tutorial of the new features and gestures?

For example, on the new Today view in notification center; will there be something to let the user know that it's new and you can do such and such, or do they "expect" users to know this? Or, the new control center? Or better multitasking features? etc etc etc.

I've been quite curious to how this might work. What do you think?
