A couple of observations. All of the UILocalNotification API has been depreciated and a new framework introduced called UserNotifications. I suggest you take a look at it. Lots of the app delegate protocol methods are also gone, see framework for new API.
It appears that a collapsing feature has been included in the API so like notifications could collapse into each other. This might make the new look make more sense but I haven't had a chance to try it out yet.
Also, when you use TouchID now, it doesn't automatically unlock, as pointed out by Craig in the keynote at time 50:50.
Finally, the reply to message is indeed an option to turn on and off for availability on the lock screen. See Touch ID and Passcode in the Settings app.
