If Apple has proven anything, it's that they understand that "design is not how something looks, it's how it works".
Ive was put in charge of "human interface", not graphic design. In other words, he's not just re-skinning iOS or re-photoshopping the icons. iOS will almost certainly display new graphics, fonts, etc. But if Apple is the Apple I know, they will also tackle various usability issues as well - over-reliance on the Settings app, annoying pop-ups and notifications, repetitive sign-in processes, difficulty sharing content, etc.
Why would this year be any different than the past 5?
Apple doesn't give users what they want. Apple gives users what Apple thinks they want. Apple knows best. They tell their users all the time.
You don't know what you want. Just leave it to Apple and you won't be disappointed. Again...
