I really feel that most leaks are intentional in order to generate buzz, and also to get people ready for big changes.
I've been thinking about it, and as someone who's not entirely sold on losing the home button and ToichID (or the headphone jack before that), if these big changes were sprung on me during the keynote I would be like, "Hell no! Are they crazy!? I don't want that!" But having weeks/months to mull over these changes and think about the pros and cons and how they will affect my usage, I may still be uncertain about them, but I'm certainly more open than I was when I first heard about them.
