What features are let for iOS 8?

So we got iOS 7, with it's new coat of paint. Jony Ive has stated in a recent interview that "design is out of the way," implying that iOS 8 will be about adding new features. For the most part, I am very happy with the features added in iOS 7. I COMPLETELY disagree with The Verge (Josh, Niley, and David's) criticisms of iOS 7, I love it both visually, and increased functionality (Background downloads, new multitasking, command center, etc).

What is even left for iOS 8? It seems like all of the high hanging fruit, and a lot of the low hanging fruit is plucked.

The only things I can think of are:

1) Quick reply with messages (like in Mavericks)

2) Siri API for third party apps

3) Touch ID API for third party apps

Honestly...what else is there? I'm curious to what people think?
